If youre really smart, you will observe this webpage closely and see who not to take advice from. You wont make any money doing it, and everyone on this page will reply saying the exact same thing and its a better idea to go to college. But, nothing can convince you of that, Im sure, so if you feel it what you want to do, just remember its not playing trains, and dont be a railfan on your interview. If you get hired, dont be a railfan, and dont try to do solve every situation that comes up because chances are youll have idea of some experienced solution you might see.
