Donīt want to sound like your Dad here, but being a university graduate does open a lot more doors than pulling out.
However, committment is what enables people to succeed in this business (amongst other things e.g flying aptitude).
Do you just want to be an instructor or do you aspire to the airlines?
If it is the latter, the best thing you can do is raise the finance (career loan, scholarship or self funding) and do an integrated course at Jerez or some other organisation. Bear in mind that the minimum course costs could go up depending on how you perform. You will also need to factor in general expenses for 14 months.
A good school should invite you for an assessment first to test your ability with basic maths and science aswell as hand eye coordination, reasoning skills and other aptitudes needed for becoming a pilot. If you donīt have these then you have potentially saved yourself tremendous expense and heartache. Other schools may simply invite you to suck it and see what happens.
Upon graduation, you will have the minimum qualifications to apply directly to an airline. This is by far the preferred route for airlines as it presents the least risk option for them especially if you leave the school with a recommendation - trust me, I did it the hard way (the former) and it has taken considerably longer to secure an airline job.
It may be several years before you have paid off your training debt, but after a few years flying in an airline, you are in 'the system' and if the market stays bouyant as it currently is, it will be money well spent.
Beware - there are no guarantees of getting a job!! so make sure that you have a back up plan if you are considering taking out a loan.
If you genuinely want to be an instructor then ask yourself why. Do you have a strong vocation to teach? Are you prepared to work for peanuts at the beginning? Instruction has its rewards, but like all jobs, you need to get the experience first before you will be able to teach and earn a decent living.
Hope this helps
