The best way to learn to fly is to do it
Contact---instrument--- aerobatic---formation[optional]
make sure you know how to fly multi's as there is a very important Vmc min contol speed demo that you need to understand COMPLETELY if ever your V1 [takeoff decision speed]=Vmc ... get some glider and seaplane/ski plane training ---do a CFI rating you should acquire about 250-300 hrs of quality experience rather than waste your money on the ripoff fastbuck programs out there today---and you'll actually know what you're doing.
Some may object and say airline flying and "barnstorming" are different sets of skills--- true, but before you deal with EICAS, MCPs/ AT/AP/FD/PFD/ND---It's nice to actually know how to fly!!!
