If you've got two or more flight schools that look good on paper and you can't decide between them, visit them and see how they strike you. It may be that one's "personality" really clicks with you, while the others leave you flat. This makes the choice a lot easier.
Try to determine what if any obstacles you have for yourself before you go and enroll in a flight school. Look into and see if you have any restrictions that will not allow you to fly before you go and invest money to learn you will not be able to be licensed for flying.
