Problem: How can I be a good friend to so many good friends?

So maybe some of you can relate and hopefully give me a little advice. Summer has brought along a little problem that I wasn't really expecting. Somehow I've managed to have too many friends. I know it doesn't really sound like an actual problem, and believe me, that within itself is not a problem. The problem is that I have so many of them that I really appreciate and cherish, and I'm finding it rather difficult to make enough time for all of them, not to mention my family. I have my best friends from high school, all my friends from school, other good friends from junior high that I still like seeing, my boyfriend, and my family. 

So seriously does anybody have a solution for how to make time for everybody? I am at a loss.
