College is easier because you have more control over most things. High school wasn't far removed from a prison routine with all the bells telling you where to go, people timing you on bathroom breaks and administrators that spent a significant portion of their time dealing with disciplinary issues.
In college, the whole system is set up to let you fail or succeed on your own. I like that, and it makes things easier. There's also a more professional environment, and it doesn't have the feeling of something that's "required" as high school did. People aren't in high school because they want to be, they're there because they have to. As a result, there's less focus on learning, and more focus on the idiotic social aspect of it, "fitting in" and all the unwritten rules...ugh I'm so glad I'm out.
College has a wider variety of interests, and there's bound to be someone else (if not a group) that share yours.
