Aviation certainly has its costs and rewards. Its much like profit/loss account.
On the one hand I have missed hundreds of good nights out, holidays and fine times with my school year chums because of weekend volunteer flying and being away on courses or not having money due to training. On the other hand I have met hundreds of great people through flying and made a wide circle of good friends from a diverse geographical, social and personality backgrounds.
I've lost at least two girlfriends through aviation but then I've made at least one and gained plenty of 'good times' from others. You'll find the airlines a particularly target rich environment when you get there Luke...
Aviation has cost me a small fortune but then my wage slip now is pretty good and in the next five years will probably suppase my best expectations.
I've suffered rows worry and confrontation at home in the family because of the time, setbacks and money aviation was costing. But know it gives me a great buzz to watch how proud my family are explaining that I'm an airline pilot...
As I said - profit and loss.
In the end it has balanced very nicely in favour of aviation for me at this point. I am sure Luke that it will do the same for you in the near future.
Good luck,
