10+ years of casual #linux user. Now in #NixOS for 1.5+ years what a journey.
One thing I learnt about myself over the years is that, I might not be a pro Linux knowledgeable guy.
But my tenacity will push me to learn things deeper & deeper when things go wrong. I know I might not be the best at Linux, but that won't stop me from digging deeper when something goes wrong. My tenacity & the way I blend multiple domains to other domains is my skill I guess i.e Creativity
Maybe this year I'll find my career path and move steadily. And no matter what, I won't give up on the skills learning. Coz that's my passion not for the sake of any Job. That way it'll stick with me and let me cross some tough topics for me to understand.
I know I can't be the best of something, but I wanna be the best version of myself

Also check these slides out, which also works as a self explanatory blog like reading about nix shells. Made it for a workshop months ago in a regional open source conference, made for beginners to intermediate.
