If you are fit and healthy with no medical history there is very little chance of failing your medical - colour blindness is just about all that comes to mind
So I would stop worrying
However my hypothetical answer is to steer clear of an industry that is low paid, cyclical and insecure. Most pilots do what they do because they want to fly and despite the rest of the job! Get a degree and look at other avenues involved with aircraft - design, r and d, management, leasing, the travel industry, filming, the oil industry. The list is long
Good luck
