Well Vin Diesel you are exactly in the same position I was some years ago. I started doing some training out in weston with cash from part time jobs but knew I was not going to be able to keep current, with limited chances of getting the Aer Lingus sposorship at the time althought I did get to the last handful or so. Anyway I would see countless amount of students in Weston go hell bent for leather towards the rating's but to only run out of cash and then lose interest as they were spending more and more cash just re-capping there last lesson cos its been 2 months since they flew. If you plan to go all the way to your cpl/atpl's I would suggest go to college work part time, get a reasonable job and work full time for a year or two and tackle the training with a wad of cash.You dont have to do a 4yr degree, do a cert or dip prefably in a technical subject and you should be sorted.
But don't attempt the training if cash is an issue you could get to a crucial stage and run dry. And keep reading those books.
I am 23 now but not for long and about to start training it took me years to save and drove me mad not been able to fly in the mean time but I still believe I have taken the right decision, and when I finish if there is no job I can still go hr build/FI/or aerobatic course or just clean planes in weston whichever but I will not have the worry of bank debts. Good luck
