While I fundamentally believe I experienced the phenomenon PG writes about, there's something to be said about the scale of it. Taking a sufficiently generous interpretation of his essay, an admirable goal for self-growth is not to work hard all the time but to develop the self-discipline to work hard when you intend to be working (with the restraint to not be working when you intend to not be working, and the internal clock to help you schedule the two at whatever the correct balance is for your life).

Perhaps as a life goal as I enter my 30s, I should endeavor to revisit my love for mathematics and computer science (as opposed my work-life-balanced but frankly boring current career path), using both the restraint and discipline I've learned, so to not make the mistakes I made in my early 20s.

After leaving the work-always atmosphere of CMU, I moved in with my then-girlfriend (now-wife) and committed to working exactly 8 hours every day to keep work from taking over again. Trying to cram all the ambition and passion for work I once had into 8 hours of junior dev work basically turned me into a soup of anxiety, inferiority, and resentment[0] for some time. I thought I was wasting my career, after trying so hard in college. It took years to reorient my priorities (and also to reach a position that was a bit less meaningless than tech support for Matlab).

I think nowadays I could do better. Maybe next time a hip startup emails me with a job opportunity, I'll give them a call ;) thanks

[0] Anxious to try and find ways to work harder and achieve more in a bland corporate environment where the build system was more of an obstacle than the actual project, inferiority compared to the success that some of my still-overworked friends were experiencing in silicon valley (with opportunities I didn't have in Boston), and even occasional resentment towards my girlfriend, for whom I had chosen to restrain myself to 8 hours of work a day, because I felt I could do such great things without that limitation.
