What is up with all this nervousness to continue ones education?
Just do it! I'm working full time (enlisted AF), and taking on a full course load through distance learning. Substitute the full time job for a full time flight training environment next summer, and I'll still be taking on a 12 or 16 hour semester next summer.
Just do it! Quit asking others if they think you can do it. Only one who can anwser that questions is you. If you continue to second quess your potential, don't expect anyone else to give you much credit for any potential.
