>>620424A live worm on a hook under a bobber is pretty hard to mess up. If you throw it somewhere there are fish, you'll almost definitely catch one. For learning techniques and stuff though, if you have nobody to teach you, it's time to hit youtube. You can find lots of how-to's.
When I first started fishing and had no guidance I made a lot of dumb mistakes that I didn't even realize, mostly involving using lures and tackle completely incorrectly. I'm still fairly new to it all but I've gotten a lot better. A lot of that is from watching people on youtube who know what they're doing and just from going out and fishing of course and picking things up as I go.
I also picked this book up and while it's really eclectic I feel like it helped.
