I agree with the if-I-could-redo-this statement I would tell myself to set aside time, at work even, to go deeper on the things that I didn’t know.

Spending time to learn things usually pays off. In recent years, I've seen students try to solve problems by searching the web for "solutions". The result is often a cobbled-together mess, with unused variables and and the inclusion of a wide range of libraries to tackle problems that can be handled in the base language. I fear that very little is gained by this. Stackexchange and similar sites can be good tools for those with experience, but they are ruinous for students who are just starting out.

When in doubt, read the documentation.
