The enthusiam is great. Keep it up. But realise one thing. It WILL be a long road. If you're going to try ATPL you will need to hour build like crazy and that costs money. If you can get a job doing it then that's a start but the scholarship places are thin on the ground and there are LOTS of applicants.
It's the same for the military, they get LOTS of applications and even many those selected will get chopped during their training. As long as you're prepared to work hard, learn lots and keep yourself out of trouble then you're in with as much chance as everyone else.
if you just want to go flying? then you're already on the road to getting aloft. If you want to get paid for doing it? Just ensure that you're aware of the journey you are about to embark upon.
If this sounds a bit disparaging it's not meant to be. But if you're not aware of just how tough the market is then you'll be heading to disappointment. Study hard, work hard, get good grades,
Good luck with all your endeavours.
