A320 - well done man.
Good choice. You will learn so much about yourself as a pilot by instructing. Sure the pay isn't great, but it is rewarding. It is so gratifying seeing your student solo, pass their checkride etc. You will feel great.
Plus you won't be in a lot of debt and you will be much more respected by future captains that you fly with when you get on that A320. And those PIC hours will slowly be adding up.
Also, try to get a part time job that will help with the bills. And the biggest thing NETWORK, NETWORK, NETWORK. Cause the guy coming through that door to get checked out in a 172, just might be a CP with some operator.
Good luck and again wise choice. Enjoy and keep us posted of your progress.
Cheers!
