Some people drop $300k for law school only to aspire to become a baker after they graduate. Life is a funny thing. I think you may be experiencing a sort of self development crisis here, irrespective of whether it's for flying or something else. I think we can all relate to that. You only got one life to live and it's important that you're happy. If you think being an airline pilot is going to make you happy then aim for the moon and see where you end Up. But you also have a family too and its inportant that they understand what THEY are Getting into as well. Be honest with them and dont neglect the facts while you follow your heart.

E.g. I once expressed my airline pilot aspirations to a retired airline captain. After he told me that I can expect to live in a hotel room for 200 days a year, I think that just about did it for me, and my girlfriend lol.

Best of luck!
