Wanting something isn't enough to make it happen. The major airlines don't hire everyone. There aren't enough open positions, and so many people want in that the airlines can pick and choose, and have always been able to do so. There are tens of thousands of pilots who meet the technical qualifications at any given time, and a hand full of openings.

Recognizing that there are no guarantees, and understanding that the major airlines are not the only game in town, it may be wise to broaden one's considerations for employment.

Honor your goals. Shoot for them, pursue them, chase them down. It's foolish to jump with just one parachute. Always have a reserve.
