Hi,
Just go for it! Its worth it...even with all the problems in todays industry (pay 2 fly programs etc).
I was aviation enthusiastic since my early age (like all of us), but somehow ended up studying something completely different and started to work in that field.
While i was working something that i really don't like, I got my ppl at age of 23 and later on spend all my free time at local airfield (skydivers dropping).
Later on i got my FI for SEP and later (at age of 31) I got my ATPL theory with CPL IR ME.
2 months later I landed my first airline job in national flag carrier.. Well, I'm still stuck on turbo prop, but that will change soon (I hope).
In career paths there are ups and downs, but its important that trend is moving up.
Cheers,
Z
