You are just another of the mass of people who dream of flying for a career. The dream is STARKLY different from reality. However, like most that have come before you, you'll need to experience it for yourself to really judge.
My greatest advice is to build credentials outside of aviation and fly for fun. When you get to a point where all your ratings are in the bag, then figure out whether its time to jump in or not.
As for me, I spent many years acquiring all my ratings while building credentials toward becoming a CPA. I built up some money as such, then decided to try aviation professionally. I did that for just about 2 years before being thrown on the street. The door will stay shut for 2-3 more years as age 65 goes through, pilots are recalled, etc. After that, I just might go back. However, I'll use my CPA credential to hedge against the cycle - so that I don't really NEED the job. I've also decided to have a child during the next 2-3 years when aviation jobs are at a low. If after having a child and being home every night to experience that, and after knowing what I know after 2 years of 121 flying, and after having worked as a CPA for another 2-3 years, if I still long for a jet cockpit, I'll give it another shot.
I don't consider my path a model of perfection. However, if you put all your eggs into aviation, you'll be sorry you did. Prepare yourself to do something else in parallel with aviation, then jump back and forth as needed.
