I wish I was better at solving my own problems. But also depends on what you consider solving your own problems is, exactly.
I learned early not to rely on other people, so I tended to look up everything I need in books and online.
But some problems are not solved with research, or suggestions from others online.
Some problems are only solved by giving yourself time to process them yourself.
This is something I'm still lacking in, perhaps because I always searched outside of myself for solutions.
I'm amazed by the solutions some people can come up with without having access to information from books/online.
