Get your four year degree first. Your young and there is plenty of time for you to fly. The 500 TT and 50 ME time requirements that you see now in my own opinion is as good as gone. You have many pilots with a lot more time then that going for the same jobs as you. Also don't just build time to build time. Have fun while flying and get your CFI and instruct. You will learn a lot and if you have good students you will have fun too. It will also afford you the opportunity to build time for free. I think to be competitive in the real near future you will need at least 2500 TT and a 4 year degree to even be looked at. Just my .02
