A couple of thoughts.

1. Working more than 20 hours per week and doing school full time is a dead end. You seem to have already realized that.

2. A work trail is a good thing even if it's piddly jobs in school. You also need the money, and having to work makes you realize how hard paying for flight ratings is. One of the best things I ever did was drive a dump truck while I bought my flight ratings, because it made be grateful to be flying.

3. The line service job you had sounded good. You can meet people who can help you later on.

4. You may not want to be a pro pilot when you find out what the job pays. I am not trying to discourage you, but keep studying it. At the least you are in for a long uphill climb making peanuts working your butt off. That gets tiring when you are 45 living out of a dump.

5. You need that college degree to have a real future in flying. The bar is high for career pilots and they all have college degrees. Just get it in business or management, you do not need a fancy degree.

6. Do not take out any loans for flight training. Pay as you go. Loans for flight ratings are insanity. I paid as I went for all my flight training, it took a little longer but now I have zero debt. Don't get in a hurry to start a $18k per year job followed by a furlough and a job at the FBO line.

Good luck.
