right here i am going to try and teach you to get good
getting good is mostly about confidence and thinking propally.
point 1
dont put your self down and dont let others put you down. the worst thing you can do is say "i am useless" because with that atitude you'll end up useles. if any1 says your crap just dont listen egnor them completely and keep a positive atidude because you can get up that big wall and you will do that big drop off.

point 2
every time you learn a new move look and think "what can i do to improve this move" try and add a bit of flare to it " like get to the edge of the wall and cross your bars before dropping. and instaed of just pedal hopping off it start at an angle and pivot before dropping. its these small things that will get you noticed.

point 3
when going off a wall pic a spot to land. even if its just a crack in the floor try and land on it and if you dont land on it try again and again. ok so you can do the 6ft drop off and you can 360 but can you put the bike where you want every time. its this sort of thing which makes you a better rider and will help when you are in situations where if you dont hitthe rite spot your screwed.
