My experience has been that "being yourself" is the best way to proceed. If you do what you like and what you're good at, the "competition" will not be a concern. YOU can be the competition for others after you get some experience, but that is going to take time.
Yes, "getting into the business" is hard, but if you're willing to work at it, start at the bottom and stick with it until you gain some experience and connections, it can be done. Speaking of "connections", you will make those in EVERY interaction you have. Pay attention to everyone you meet, and try to stay in touch, however loosely, as you continue in your career. "Connections" are just the people you know and the people who know you. Go for it!
