You only come out of school with the talent that God gave you. Schools help you refine these things. Are you a hard worker? Are you willing to learn from the old timers and not present yourself as a know it all? Are you happy with what you're doing? Are you willing to ask questions? You willing to exert the effort into your work as if the work you're doing was for yourself and not a customer? If you ask yes to these things then don't worry you'll be alright. You only pull as much out of this life as you're willing to put into it. No one owes you a living. This may be a platitude, but don't ever let anyone convince you that you can't because if you really want to achieve something you can!
