I will say one of my career regrets was kinda being dogmatic about boring tech instead of being pragmatic e.g with new tech

there was a period around 2016-17s when people were building stuff with Node.js | Mongo. but it was risky tech though I had experience in it & turned some of those opportunities down cz I wanted to work with boring ruby/swift(iOS stuff) lol. rookie mistake.

fortunately the market made me wise up - you go where you're wanted.
