I cannot enough emphasize the importance of reflecting and learning from experience. Therefore I recommend to spend some minutes every evening to reflect the day and to draw essential insights. Try these questions for your reflection:
What can I learn from what happened to me today?
From the positive but also from the annoying or even painful experiences?
Can I draw any important insights which will help me to cope in a different day with similar situations in the future?
So what have you learnt today?
