I was on my way starting masters on Mathematics when I discovered I would be a father, I had to find and start a career so that I could make ends meet.
From my perspective I am glad that happened, I was excessively ambitious, comparing myself with the great ones in the field, measured my self-worth on regard of my ability to solve problems.
Having to swallow my pride, learn to talk with other people as equals so that I could provide for my family made me a better person. I am not sure I would have done this breakthrough isolated on my intellectual bubble, not even talking about the difficulties of engaging with egos at the academia.
Sometimes I miss the excitement of learning something really difficult or solving some problem from a new perspective, but I am glad I am mentally healthier. I am not saying that it's not possible to be healthy and pursue a high level on Mathematics or other intellectually challenging field, but that can enable bad patterns for some people.
