couple things:
1.) don't spend too much on the board.
2.) do NOT learn tricks on carpet, because you will be utterly fucked when you try and skate anywhere else. (unless you already know them and you're just working on them).
3.) you will fall, a lot, don't take out your anger by throwing your board at passing cars.
4.) a nice blend between super smooth pavement, and rocky pavement is the nicest (I find) because it will be easier to ollie but you will also be able to push without too much difficulty.
5.) after you discover the newfound power of oillieing, don't just flip your board as hard as you can to see if you can tre flip or triple kickflip or something. your balls will thank me later.
goodluck!
