Flying is not hard. Almost anyone can learn to do it. A lot of the training is mental and done on the ground, like learning your regs, airspaces, ATC communications and procedures, etc. But not hard. You learn to fly like anything else you learn: One step at a time. If you do decide to take flight training, I would offer one piece of advice - have all your money needed for training saved before you begin. If you run out of money in the middle of your training, it will cost you more when you resume to cover refresher flights for lessons you have already completed. Someone above said you could get a private license for about $4,000, but I think that is a low estimate. Plan for somewhere between 5-8 grand. It will depend alot on what flight school you go to, how much aircraft rental and instructor fees are, as well as your own proficiency, but it will be somewhere in that range. If you want to see what it is like before committing a lot of time and money, go to your local airport and take a discovery or orientation flight. An instructor will take you for a ride and let you take the controls to see if this is something you would like to do. Happy flying.
