Goals.....?

Life is so much harder having no goals.... I continue to stress because I have no goals. Having no goals I feel undefined. I search my head and goggle careers, but I'm not interested in anything. What am I good for? What have I been doing with the last 23 years of my life. The Navy seems like an escape all of a sudden. Many ask why I'm doing it, and I have an unclear answer. I joke and say because I look good in white and I get disgusting remarks. I feel its a way for me travel and see more of the world experience something different. Its a tough commitment but so is having a child or picking what college you want to go to. I don't know the less I bring it up or the less its brought up, I feel better. I still feel lost though. Part of me still wants to be a teacher and help under privilege kids who don't have the money to be successful. And I can't forget about the parents working several jobs just so there child can have a normal life. But I;m also faced with my other side who feeds off of greed and  thinks of himself and just wants to the gym have that amazing body crush everything around him and feed off the weak. Have that 6 figure job and all the women in the world.
Some tell me I've accomplished so much for my age, but I disagree... WHy doesn't my GPA show it? Why did I work so hard in the YMCA only to be forgotten and be remembered as the asshole. Why did particular girl friends leave me? I feel it all comes down to not having any goals. What is a goal? And if its completed whats next? I have to think about another goal? When does it end.
