#1 by far, don't get frustrated when things don't go your way.
#2 I have to second what Kris Martinson said. I have learned so much from this site and I can't believe how many great friends I've met and made here on SSV. I did watch some Youtube videos just to witness technique but the overall wealth of information that is here is just fantastic. I have asked a ton of goofy questions but at the time, I felt that they were important. At least to me. I have gone clear back and re-read everything that I posted or asked and I wish there was a way to delete a bunch of them. I'm actually embarrassed when I read them now.
#3 Also , don't get in a buying frenzy on blades. Buy a couple of sizes of one brand and get used to them. After you gain some experience, you'll then have the knowledge of what to look for in a blade. There are so many to choose from that it gets expensive just to have a bunch of blades in a holder that may never get used.
