FYI If you know that you will like skateboarding don't buy a Walmart skateboard like I did! It is terrible and actually makes learning it harder and may even discourage you because you may think that it is you. Hey, I get frustrated a lot, but when I had that lesson, and I used my teachers skateboard, it was noticeable different. So don't worry, try things out and don't get discouraged.
Neat fact:
If you push off with your left foot. Its considered a trick. (can't remember the name ) I naturally push off with my left foot. It is actually rare for a person to do that. I'm not sure why but it is. So if you do that, just know that you are unique in one more way. :-)
