Spend more time around people. If you want to make friends, you first need to put yourself out there somehow in order to meet people. If you're still in school, sit somewhere with other people, it doesn't have to be the 'popular' table, or a crowded one, but one with at least two other people. Because the 'populars' won't matter when you're older but a true friend will be there for you forever if you're true to them. Remember, friends seldom come knocking on your door while you sit at home playing computer games. Populars aren't always going to be mean to you. They just need to know you a little better.
