Go Fot It!
I think 29 is not too old to get your dream started but I would suggest that you map out your training path and remain FOCUSED! Get your wife to participate in the planning coz it ont be all too rosy and if she's in with you, that's great. There will be a lot of ups and downs so teamwork will be crucial.
If you eventually would plan to fly in the Phils, I think a degree would come in handy so consider going to night school to complete even a 4 yr degree. Good luck !
