10 practical lessons from Fooled by Randomness by Nassim Nicholas Taleb

1. Understand the Role of Luck
Keep in mind that luck is a big part of success. Many results that people think are due to skill may actually be caused by luck. Being aware of this can help you stop being too sure of yourself.
2. Beware of Survivorship Bias
Be careful not to jump to conclusions based on examples that worked without also looking at examples that didn't. This bias can change how you see the world and cause you to make bad decisions.
3. Accept Uncertainty
Accept that living and making decisions are always uncertain. You can make better decisions and feel less anxious when you accept that you can't always tell what will happen.
4. Differentiate Between Skill and Luck
Learn to tell the difference between cases where skill is needed and ones where luck plays a big role. This knowledge can help you make decisions and figure out how dangerous something is.
5. Focus on Process Over Outcome
Put the process of making decisions ahead of just the results. Due to chance, even good choices can have bad results, and sometimes bad decisions can have good results.
6. Avoid Overfitting
Don't try to fit complicated facts into simple models. When things aren't clear, making predictions and choices based on too much past data can be wrong.
7. Develop a Long-Term Perspective
Don't just focus on short-term changes and results. Focussing on the long term helps you see the bigger picture and not let short-term trends or losses change your mind.
8. Cultivate Intellectual Humility
Recognise the things you don't know. Realising that you don't know everything encourages you to keep learning and be open to new ideas.
9. Use “Negative Visualization”
To get ready for possible problems, practice picturing the worst-case scenarios. This can make you stronger and help you see what's important more clearly.
10. Be Cautious of Experts
When someone says they are an expert in a subject, you should not take their advice at face value. Experts may not really understand chance, and they often think they can predict the future better than they can.
These lessons make people think more deeply about chance and how it affects life, which leads to a more resilient and well-thought-out way of making decisions.
