you don't have the time because you spend it bruteforcing solutions by trial and error instead of reading the manual and doing them right the first time

I feel like your working environment might be to blame: maybe your boss is too deadline-driven so that you have no time to learn; or maybe there is too much pressure to fix a certain number of tickets. I encourage you to find a better workplace that doesn't punish people who take the time to learn and improve themselves. This also keeps your skills up to date and is helpful in times of layoffs like right now.

Seriously? Yes, you should read the docs of every API you use and every tool you use.

I mean, it's sort of ok if you read somewhere how to use it and you use it in the same way, but I, for one, always check the docs and more often even the implementation to see what I can expect.
