I had the same problem. I think your probably afraid of sliding off the road. Well I am sorta too... but the way I learned and started to progress was to not be so afraid. I'm not saying go do a suicide drift or anything (like 100mph braking drift on a 90* corner). But just go at it a bit more aggressively and see what it's like. You have to understand that if your going to drift, you WILL hit something eventually. I'm just luckier than most... I have had several close calls.
