I need a job..

What I would really like to be is a proffesional race car driver; like in the rallys and NASCAR and drifting and all that.
Obviously you need to be able to drive and be fearless and all that.
But I was wondering how one goes about actually getting a job as one. Because surely, you cant just turn up one day at one of these events and be allowed to race.
Hopefully you dont need a degree or anything for this sort of job...
