NSO - Im giving up a financially rewarding career as an accountant to do this. As very well said above, if you can accept the risks involved then it will be fantastic. I mean, what better feeling can there be than conquering your life ambition!
If you get a decent job and your family are ok with it then it'll be worth it but on the other hand if you look back in 5 years without a job, in **** loads of debt and no real way back to your old career then obviously it won't have been worth it.
For me, Im risking enough at 22. Would I do it when Im married with Kids and a mortgage...probably not. But like everything else in flight training, how you go about it is a very personal thing and has to suit your circumstances.
In short, the decision has to be yours but good luck and I hope all goes well whatever you decide.
