Have you been practicing and not making progress? Or are you complaining because you can't do the things you see other people do, but not really working on your weaknesses?
No you're not alone, I consider myself lacking skill too. But that hasn't stopped me from getting out and having fun, and I'm seeing some improvement. Keep at it and you'll get better.
just get out and practice, i switch off one day ill ride 14 miles on the road for fitness the next day ill go hit some trails in the woods or just putt around town trying to do wheelies and bunny hops for a few hours..
