Collaboration is hard.
I wish someone had told me that it is supposed to be hard.
In school and college, the assumption often seemed to be that just the act of putting people on a team would somehow induce teamwork. No one taught the members how to actually collaborate.
If you didn’t get along, you just divided the work so that you could avoid each other. More, it was short-lived — on the next project you could team up with someone new.
It was when I started my first company and the stakes became real, that I learnt how hard it was to work with other people.
There was no next project. I was stuck with my co-founders, and they were stuck with me. It wasn’t about getting a good grade, it was about our lives.
