If you want to fly because you love flying then the other option is to get a good job and fly for pleasure. I have several friends in the airline industry and frankly on balance I'm glad I didn't do it.
As a private pilot I can go where I want, when I want with who I want. The flying is still (probably more) enjoyable as it is hands on piloting skills 100% of the time and you fly low and slow enough to take in the sights. It's surprising how many airline pilots also fly light aircraft. Why do you suppose that is?
However having said that, if you have a dream then go for it because if you don't you will always wonder 'what if?'
