Just got for!!!
Passed my CPL flight test a few weeks before my 18th b'day and i've had my CPL for just over a year now.
There are many pilots out there that started out when there are right out of school turning 18. If you work hard, act profesional and try not to party too hard while doing your training people will take you serrioulsy and not just some "kid" spending their parents money.
If things don't turn out as planned you can always change paths and go do a degree as you are still only young.
best of luck with everything
PM me if you have any other questions
