This is the second time I've seen you post that picture. I find it to be pretty obnoxious, because I remember when I first joined I was really worried about putting stuff in the wrong section or sounding like a newbie. And I don't care if you're "joking".
On topic: All the advice given above, but just remember, don't slow down! It's scary at first, but the faster you're going, the less time you're on the rail.
Keeping a good speed is especially important as you move onto bigger stuff. (I've gotten stuck at the top of a rainbow.)
