I've been writing since 2016 and have covered a wider range of topics that I ever expected. Initially it was just somewhere to write about the the programming concepts I was trying to learn. It's become my personal archive of resources and notes.
My wife was enthusiastic about it and gave me the confidence to quit. Until then I'd been looking to get the transition locked in before quitting, which wasn't happening and probably never would have. At the time I was working in corporate finance and my first child had just been born.
I think the added pressure of being scared or uncomfortable gives you a huge edge when learning new skills, taking calculated risks and trying new things, and working super hard. Working hard in a grind or dead-end is sole destroying (I think), working harder on something you chose, with tangible personal benefits is exhilarating. My career took a new direction and a much steeper upwards trajectory.
That was 3 years ago. I've become a freelance data-scientist, working remotely in a new country, with a much higher quality of life.
