Keep your bike dear, but I'm thinking maybe you should spend some time on a dirt bike. Nothing huge maybe a 75 or 100cc. This will (IMO) help you feel what a bike feels like when the rear brakes loose or you slide alittle without the drama of being on the street. You're out there in the dirt, no one around you, so you can "play". See what its like to come to a skidding stop or power out of a rear wheel slide without the intimadation of the street. Get your gear on and if you fall or the bike slides out from under you, no biggie, you're on dirt and not going the fast, get up, brush yourself off, and get going again, this
will help you. You will get your balance and confindence, this is priceless experence for the real street world.
P.S. I have to do this:
Just kidding,
