This question is kind of weird, in the sense that what I really wish is that I had climbed some shallow (big wins with not too much effort) learning curves earlier. In lots of domains, an 80/20 rule applies, where you get 80% of the benefit with the first 20% of the effort expended.
I'm curious about the domains where you get shallow wins.
This is the question asked by John Cook on Twitter. He lists responses from different people:
Mine are: quantum mechanics, Python, cooking, the language of philosophy.
What learning curve do you wish you'd climbed sooner? Give reasons and stories if you feel like it. Do you think other people should climb the same curves?
