Agreed. Don’t be afraid to ask questions and for help. Everyone starts somewhere, and most experienced people will be happy to help you as long as you don’t act like you know it all. Nothing is a a bigger turn off than someone with little knowledge or experience who is not willing to listen to advice. Not all advice will always be good, but be humble and keep your ears open and mouth shut (unless you’re asking questions for the sake of learning).
Read, read read and then read some more, just don’t believe everything on the internet. There are lots of clueless individuals posing as experts on the web. All someone needs is a keyboard and an internet connection to be a master tech/ tuner/ fabricator/ etc. Learn to spot the phonies. Read manuals, technical books, and everything else you can get your hands on, then go out and get dirty. If you can, get an experienced person to look over your shoulder when you first start wrenching yourself.
Good luck and have fun.
