I feel humbled on how much there is to learn.
Sometimes, I feel envy towards the (often) younger people who are happily optimistic and ignorant of so many things.
This is explained by the Dunning-Kruger effect:
What I am trying to say is that best moment to learn is now.
Learning is repetition.
Ignorance is one red flag.
Arrogance is another.
Therefore when around others, lean in, listen more intently, take notes more fiercely, be more present and ask better questions. You will learn more intently.
Compare your notes after wards with others. Discuss.
Revise your notes regularly.
You will learn more intently.
