not really a tip but....
it takes FOREVER to get your first win, but as soon as you have it they just keep on coming, so stick at it

i find that improving in your own races rather than trying to win other people helps LOADS.. eg, tring to beat the amount of laps you do each time you race, or try and knock as many secs off your laps.. i find it helps me lots cos im not cometetative at all, the most competative i get is when i find a driver that is about as equally skilled as i am, and just pretend im only racing against him, and see how many meetings it takes before i beat that person afew times, then i can see how fast im improving
