Replying to Any one else want to be a race car driver?

So lately I have been thinking how badly I would love to race car's and be a driver. Every time I drive my car I always find it to be so exhilarating. I went to a go karting place once where they have to fast kit carts and the guy working there said that he had never broken 25 seconds on this course and he had been working there for a while and I broke it my first lap. Is this just a childhood fantasy that everyone has or should I try and pursue this dream?
