dont give up...consider your self like michael jordan who was cut in high school keep practicing...I was getting frustrated myself trying to do 5's but once i got it I was so pumped the feeling of knowing you stomped it is incredible and it keeps you coming back for more...just start out small and work your way up, what i have found works is to try new tricks at about 12-2 in the afternoon because your are warmed up and that is when visibility is best too, plus after about 3PM your legs tend to get tired and i have fallen on simple tricks i have dialed...just keep at it
