You have a few options, but all of them will require hard work and a serious investment of time, effort, and probably money. However, being a professional pilot for a living is very rewarding.

First, you could go through independent flight schools. The most common route is you'd get your Private, then Instrument, then Commercial, then Flight Instructor, then you'd build time instructing until you qualify to get your Airline Transport Pilot license. Scholarships and personal loans can help pay for this.

Second, you could go through a university flight program. Certain universities will send you through the above-mentioned training pipeline as part of a degree program. This bundles your flight training with more traditional education programs, so student loans and scholarships are readily available.

Third, you could go through the military. Earning your military wings will qualify you for equivalent civilian ratings, depending on what exactly you fly in the military. You will also not have to pay for flight training (at least not with money). The training you receive as a military pilot is highly valued by hiring airlines. However, this might not be the quickest way to the airlines due to service obligations, and I don't suggest anybody pursue a position as a military officer just as a stepping stone. You have to want to do it.

If you have more questions about the pipelines, feel free to reach out to me. Or, you can research the topic more on your own here.

See 14 CFR 61.109. You will require at least 40 hours of flight training, of which at least 20 hours must be with an instructor and at least 10 hours must be solo (you flying without a supervising instructor or anybody else onboard). Note, these are minimums and the national average is closer to 70 hours of training. This (normally) isn't because flight schools are trying to squeeze money out of you, it's because they want to make sure you are safe. There are some more specific time breakdowns in the actual regulation.

You will also be required to pass a written exam, an oral examination (with a check airman, not a dentist), and a practical flight check ride.

See 14 CFR 61.65. You will require at least 50 hours of cross-country time as pilot in command, 40 hours of actual or simulated instrument flying time, of which at least 15 hours must be with an instructor. There are some more specific time breakdowns in the actual regulation.

You will also be required to pass a written exam, an oral examination (with a check airman, not a dentist), and a practical flight check ride.

See 14 CFR 61.129. You will require at least 250 hours of flight time, of which at least 100 hours must be as pilot in command and 20 hours must be with an instructor. There are some more specific time breakdowns in the actual regulation. 

You will also be required to pass a written exam, an oral examination (with a check airman, not a dentist), and a practical flight check ride.

You must have your commercial pilot license and instrument rating, but otherwise there aren't many extra requirements. However, this is going to be the most difficult license you get for a while. You must not only know all the required material, you must know how to teach it and explain it. You must also know how to fly well from the right seat of the airplane while instructing the maneuvers and not letting the student get into an unsafe flight regime.

You will also be required to pass two written exams, a very lengthy oral examination (with a check airman, not a dentist), and a very lengthy practical flight check ride.
