I've never worked for any place where I felt like I was great. I've worked for places where I've felt appreciated, but never like I was great. Feeling appreciated is nice, but it doesn't mean you are doing what you want to do. In some ways, it holds you back. Constantly giving you the feeling that you are making headway, when you are really still as stagnant as you were at the job that made you feel worthless. How many times is a pat on the back and a, "Good job!", going to satisfy you before you realize that you have sacrificed five years of your life and never made your dreams come true.
I feel great when I am creating. Whether it is writing, designing, or programming, as long as it is flowing from my pen or keyboard I feel like I could be something great. I miss the feeling of possibility I had as a kid. Now I feel like time is running out, and opportunity is slipping through my fingers. The time to act is coming soon, and I must do something great. Or, forever be appreciated.
