Probably best place to start is by booking a trial lesson at the closest flying school to you and see whether you like it or not. Alternatively you could have a go in a glider for less money. It will then be easier to decide what you want to do. If you want to go commercial a private license is a good start, but if you just want to get in the air, gliders or microlights might suit your wallet better.
Good luck with it!
