Don't worry about being 22 and starting now.. I didn't even consider going to a 4 year college until I was 21.
Time sure is skewed when your 22 and maybe tired of instructing, wondering when that big break will come. Trust me, you have plenty of time. If you got hired with a major right now, you would have 43 years with them... 43 years! That is almost twice as long as you've been alive, and I'm sure you can't remember a lot of your life when you were young.
Take it slow and enjoy the journey. Go to college (not an aviation college PLEASE), instruct full time or on the side, and enjoy the experience! You married?.. Because if not, taking girls up flying will be a huge advantage for you.
btw, I only say the aviation college because I went that route. You will save a lot of money and have other skills in case you decide to back out of aviation.
Good Luck! I wish I did it that way.. state school and CFI/MEI.. oh well.
