What if you could learn to stay grounded, even when life doesn’t go according to plan? Stoic philosophy is an ancient approach to life that offers practical tools for navigating challenges, managing emotions, and finding greater peace of mind. 

Developed in ancient Greece and later embraced by thinkers such as Seneca, Epictetus, and Marcus Aurelius, Stoicism teaches us to focus our energy on what we can control while learning to accept what we cannot. Rather than avoiding difficult emotions or experiences, Stoicism encourages us to meet them with awareness, perspective, and resilience. Although it began more than 2,000 years ago, its ideas remain remarkably relevant today, offering a thoughtful way to respond to everyday stress, uncertainty, setbacks, and change.

Here are five Stoic principles from Jonas Salzgeber’s The Wisdom of Stoic Living Short Course for greater mental well-being that you can apply to modern life. If you want to live more mindfully and intentionally, while becoming better equipped to navigate uncertainty, challenges, and change, these timeless principles offer a practical place to start.

1. Focus on What Is Within Your Control

Epictetus distinguished between what is up to us, such as our choices and judgments, and what is not, such as other people's opinions or external outcomes.

Imagine preparing for an important presentation. You can practise, check your information, and ask for feedback. You cannot guarantee that everyone will be impressed.

Separating your effort from the outcome gives you a clearer place to direct your attention. You can care about the result while recognising that it is influenced by more than your actions.

Try this: Write down one current worry. Identify an action you can take, then name the part you cannot guarantee. Put your energy into that action.

2. Examine the Story You Are Telling Yourself

We don’t always respond to events as they happen. Often, we respond to the meaning we give them. This was an important idea in Stoic philosophy. Epictetus taught that it is not simply what happens to us that causes distress, but the judgments and interpretations we make about what happens.

This gives us a useful practice for modern life: learn to separate what happened from the story you are telling yourself about what happened.

For example, “My friend hasn’t replied to my message” is an observation. “They’re annoyed with me” is an interpretation. And while that interpretation might be true, there could be many other explanations: they may be busy, distracted, tired, or simply haven’t seen the message yet.

This doesn’t mean ignoring your feelings or convincing yourself that everything is fine. If someone has genuinely hurt you or you are facing a difficult situation, your emotions are valid. The practice is simply to notice when your mind may be filling in the gaps with assumptions, particularly when you don’t yet have all the information.

By creating a little space between an event and your interpretation of it, you give yourself more freedom to respond thoughtfully rather than reacting to a story that may not be true.

Try this: When you notice yourself becoming upset about something, pause and ask:

• What do I know for certain?

• What am I assuming?

• What else could explain this situation?

• What response is most appropriate based on the evidence I actually have?

The goal isn’t to always think positively, but to practise thinking more clearly and objectively, so you can respond to situations with greater awareness and choose how you react rather than being driven by your first emotional response

3. Accept Reality Before Choosing Your Next Step

Stoic acceptance means acknowledging circumstances as they are, rather than resisting reality or expecting events to unfold according to our wishes.

When plans fall apart, it is understandable to feel disappointed. You can allow that feeling and still ask what the situation requires now.

Suppose a project is delayed. Recognising the delay allows you to revise the timeline, communicate with others, and consider alternatives. Repeatedly arguing with the fact of the delay leaves those decisions waiting.

Acceptance also does not mean that you cannot take action. In fact, acknowledging that something is wrong can be the first step towards changing what you can. You might accept that someone has treated you unfairly while still choosing to set a boundary, speak up, or change how you respond in the future.

Try this: Complete the sentence, “This is what is happening, and my next useful step is…”

4. Let Your Values Guide Your Behaviour

Marcus Aurelius repeatedly returned to qualities such as justice, self-restraint, and acting with reason. A practical way to apply this is to ask what kind of person you want to be in a difficult moment.

During a disagreement, you might value honesty and kindness. That could mean explaining your concern clearly, listening carefully, and avoiding a personal attack.

Approval and achievement still matter to many of us, but values offer another way to assess our actions. Did you behave fairly? Did you follow through on something important? Did you acknowledge a mistake?

Try this: Choose one value each morning and identify a small action that would express it that day.

5. Return Your Attention to the Present

Marcus Aurelius often reminded himself that the only part of life we truly have is the present moment. Applied to everyday life, this invites us to notice where our attention is and gently bring it back to where we actually are.

It is easy to be physically present while our minds are somewhere else. You might be washing the dishes while replaying yesterday’s conversation, sitting with a friend while thinking about your to-do list, or spending a quiet evening rehearsing everything that could go wrong tomorrow. 

Our minds naturally move between the past and the future, and reflection and planning both have their place. But when we spend too much time anywhere other than the present, we can miss the experience that is happening right in front of us.

Practising presence can help us feel more grounded and engaged in our everyday lives. It allows us to experience moments more fully, pay closer attention to the people around us, and create a little distance from the thoughts and worries that can pull us into rumination or anticipation. It can also help us recognise what we actually need in the moment, whether that is to focus, connect, pause, or rest.

Being present does not mean trying to empty your mind or never thinking about the past or future. It simply means becoming more intentional about where you place your attention.

Try this: Pause for a moment and notice your surroundings. Take a breath and ask yourself, “What needs my attention right now?” It might be the task in front of you, the person you are with, something you are feeling, or simply the need to rest. Then gently bring your attention back to it.

Making Stoicism an Everyday Practice

Begin with whichever principle feels most relevant today. You might question one assumption, take one useful action, or make one choice that reflects your values.

You will still experience frustration, uncertainty, and sadness. These practices offer a way to reflect on those moments and respond with care. Progress can be as small as noticing that you have another option before you act.
