Whatever doesn't piss you off in this forum will make you a better sailor.
Or something like that.
I found that keeping a notebook helps me. I write down things I come across that I think are important to know (even if later, once I know more, it turns out to be crap), questions I have so I can ask later, and resources I don't want to forget.
Nothing beats actual experience on a boat, but until then reading, asking questions and taking every sailing and boating class that you can (weather, navigation, offshore passage making as Minnewaska mentioned), will help you reach your goal and you'll encounter fewer surprises along the way.
