Many people say that. Its good to be a little nervous but that doesn’t mean you shouldn’t do it at all. Do it at your own pace, even if it means just going straight down a quiet street in the beginning. There are plenty of people out there who can’t do too much but can drive, you have no reason to think you’ll do any less than them. Keep your eyes set on the goal, not on the road to get there! (Well… you know what I mean.)
Hatzlacha!
