I am a freshmen at a Christian college, and I wouldn't mind meeting a girl here. Is it bad to make myself become more social in order to increase the chances of that happening?
I would see it as you opening a part of yourself up to other people that you haven't before.. not being someone you aren't. As far as the girl goes, look at it this way: there's someone out there who would just love to date you, but they won't get to have that chance unless you introduce yourself and ask. So you're doing her a favor too.
I used to be really deathly shy, starting college as a freshman, about 5 years ago. I can PM you something that I swear worked for me, if you want. The brain is very suggestible. The catch 22 is you will feel stupid convincing yourself how great you are, but it works. I can PM you some info on the stuff that helped me, because I used to be the most timid person on the face of the earth and now I can talk to anyone.
Also, if you have one really good friend in your life who you rely on all the time socially, try to start relying on yourself instead sometimes, and doing things without that friend at times, or you won't toughen up. I had this problem in HS... also, my first year of College, my roomate was my best friend from HS, and because of that, I was never forced to jump out of the nest and start flying on my own so to speak.
Join clubs! Chicks dig dudes who do charity work. You'll meet lots of people at different groups for different interests. You don't have to know about basket-weaving to go to looming club, btw.
Also, if you want success with women, you have to get over Too Nice Syndrome (sorry ladies, but you made me even though I didn't want to) and start to be at least somewhat aloof, mysterious, and detached (yet friendly, just not needy) early on if you aren't already. After about two months in a relationship you can drop this gig, though.
www.askmen.com is a good resource on dating tips too.
Two rules, though: never ask if you can kiss a girl. Just do it. And when you talk to a girl, go for her home phone number. Just ask, you'll be surprised at how easy it is.
Also, keep in mind that you may have to ask a lot of girls... I know I do. As men, we have to risk and experience a great deal of rejection. You will probably ask 15 girls out. 10 of them will have boyfriends. 1 of them will make up a lame excuse. 1 will turn down a date. 3 of them will want to go out with you. Of those 3, you probably won't like one. One of them won't like you. One might be worth investigating. It's just how it is.
