An overall list of things I wish I knew:
1 - College isn't high school
Just because you were neglected back then doesn’t mean it’s going to be the same now. You are more mature, and better able to avoid the mistakes you formerly made. Other people, as well, are more mature and are better able to appreciate you for who you are.
2 - Make yourself approachable
Sit down in the cafe or cafeteria, or any place where students get together. Don’t stay too enveloped in your cell phone, sunglasses or headphones. Many people just look for a student sitting by themselves unoccupied and then approach them.
3 - Looks aren't everything
You should dress, groom your hair and the like to make the most out of your looks, but the idea that you have to be above average looking in order to get attention isn’t true in hindsight. I’ve always been a handsome man who was 60 lbs overweight. I thought my weight was a dealbreaker, but it really wasn’t. Most people think the opposite sex overwhelmingly prefers skinny people, but it’s quite the opposite. Men, despite what they may say, love bigger women, and women don’t care about a guy’s weight as long as he’s really amazing to be around.
4 - People only have high standards if they like you.
The idea that you have to have a lot of money, be the best looking or be #1 at anything is not really true. People have a list of standards, but they only apply in a hypothetical situation of a stranger or something. If someone really loves your personality, finds you interesting and has lots of fun every second they spend with you, they’ll overlook a lot of things. Think about the drug companies. They charge $200 for a bottle of pills, but that’s not what everyone pays. Most people just pay the co-pay or get it for free. Similarly, people waive their nonsense requirements in dating too.
5 - Don't take rejection personally
In college, lots of people are extremely busy with job/kids/etc. Also, some people are simply just interested in spending time with their clique only and they don’t expand their horizons. But don’t take it personally. Many people find a college setting intimidating and difficult to meet people in. A lot of people go from one class to another, crossing off the many tasks on their to-do list as they ponder whether they should go up and talk to someone or not.
