For the first two and a half years of high school I was the polar opposite of you. I had success with women, had a lot of friends, etc, etc. When I was about half way through my junior year I realized that these people I hung out with weren't going anywhere with their lives. They cared more about getting some ***, getting high, drinking, and where the parties were on the weekends than making the most out of their education and actually doing something with their life. About the same time I realized that, I got myself one good girl and focused on my education. Now, after spending four years in the Air Force, travelling all over the world, accomplishing a lot of things that most 22 year olds wouldn't even begin to understand, I understand now why I chose to distance myself from the "cool crowd". I made the right choice. Every time I go home on leave I run in to one of the people I used to hang out with and all he's doing is working at Sunglass Hut in the mall, getting stoned, and spending time in jail.
My story is not to tell you about me, but to let you know that I think you're on the right track. Don't worry so much about what others say to or about you. You're half way there. Watch out for #1, do your school work, and focus on what's ahead of you. Forget about making lots of friends and girls. Those are things you have your whole life to figure out. Your education is now and you only have this chance to get it right.
