I would say go for it 100%. Im in college right now pursuing a degree in something other than aviation. I plan to work and continue on with my ratings without taking a loan. You definitely dont want to be in the hole making instructor then regional pay for 10/12 years. Have a backup degree just in case your health goes to crap, among other reasons. Regarding finance, It is entirely possible by paying as you go, which is what I have done so far. If flying is what you want to do for a career, dont listen to anybody else and just do it. Just remember to enter the industry with your eyes wide open.
