You get one life, this is not a rehearsal. If you feel that flying is for you, go for it. You might have to do other things as well to earn a crust, but you will have no regrets. Even if you only get a few years out of it, in retirement you will be able to say 'I did it'
Unfair comment from Dog14. Because some of us were not sufficiently interested to serve in the military does not mean we were not good enough. Typical airforce brainwash which thankfully has been less of a blight on civil aviation in recent years. Military training methods and a lack of experience acting and planning within a commercial organisation are not compatible. You no doubt did a great job in the air force which has the gratitude of the 'free' world - but we also serve, and are not inferior.
