Future pilot:
If it's a passion and you feel it's something you want to fulfill, then go for it. Just keep in mind that the training costs will be high, and the road to a financially satisfying flying job may very well be a long one.

I'm 33 years old, been at two different airlines, still cannot upgrade to Captain, and my W2 has only broke 50K once back in 2006. But, I'm still happy and have not lost hope.
