Growing up means learning that many adults were simply older beginners.

At some point you notice that the adults you assumed had it worked out were improvising too. The teachers, the parents, the people running things: they were simply further along the same uncertain road, guessing with more practice. It is disillusioning and mostly a relief.

Use this both ways. Be less intimidated by people who seem certain, and be gentler with yourself for not having arrived. Nobody arrives. Everyone is a beginner at whatever stage they are currently in for the first time.
