I'm 36 and often ask myself, what did I do?
My parents had kids with 20.
My father and grandfather were managers with 25.
I met a bunch of people who founded a company before they were 20.
Friends of mine traveled from Europe to East Asia as hitchhikers in their 20s.
Many of my fellow students work for FAANG. Two are CTOs at middle sized companies and one is even a professor at university.
In contrast to that I always feel like a slacker.
