Download from the FAA web site the Pilot’s Handbook of Aeronautical Knowledge, Airplane Flying Handbook, and the Aeronautical Information Manual. Study those until you’re blue in the face. Then seek out a flight school and find out what airplane you can afford to train in, study the crap out of the plane’s information manual. Make friends at the airport and borrow training materials. Save money for flight training, dedicate 6 months of consistent training time (you’ll likely need less due to consistent training), and hit it hard.
