How often do you get what you want?

I was on facebook one day talking to one of my coworkers. Every so often we go back in forth in my comment section and I'm always amazed by him. He is so much deeper than I ever would peg him to be. I mentioned how I'm not much of a competitor. I said, "I always manage to get what I need." He questioned, "It's cool to get what you need, but how often do you get what you want?" As I stared at the question on my screen I seriously thought about it. When it comes to goals where all I have to do is "A, B, and C" I'm going to get it done. When it's just me standing in between myself and the goal I'm never going to hold myself back. If it's a job I'm going to get it. If it's a grade I'm going to get it. Even then I don't strive to do it better than everybody else doing it, I just strive to get it done. When it comes to matters of other people I will often take the L. If I want something and someone else wants the same thing I will just let them have it. I don't know if it's a feeling of inferiority because I never feel less than the next person. I just know that I can do without. No matter what I'm going to be ok. I always want to see everyone succeed. In order to make this happen sometimes I sacrifice what I want. It's not always good because 8 out of 10 people operate with their own interest at heart. I don't want to compromise who I am as a person but if I want to get what I want and not just what I need a change may be necessary. Is it worth it though?
