jaimz,
Yep, I agree if you're heart's set on becoming a pilot, crack on. But, and it's a very real but, I know several people who've splashed the cash to get all the training and ratings done to lose their medical. They weren't old at all. Late 20's to early 30's.
1 had a bike crash and it resulted in a head injury. No medical.
Another developed migraines causing visual disturbances. No medical.
A study buddy developed a condition that has left him unable to hold a Class 1.
An instructor fell over and damaged her back, no more medical, therefore no more job. To make matters worse, her employer hadn't paid the proper insurance. No money and no job.
A few others have fallen by the wayside simply because they ran out of money to keep the IR current while looking for jobs. If you finish during the early part of a down turn, there's just no jobs for low houred guys. Eventually, keeping every thing current just bleeds them dry.
You do need a back up OR a plan to take any job while waiting to get a flying job. If it means labouring or driving a truck/taxi, so be it.
