I hate when I see people complaining about how much they hate college. I get it, it's not easy like high school was, but it's still fun. If you choose to hate college then oh well, but maybe you should loosen up and have fun.
1. Forget high school.
I'm not one to really talk about this one, but I'll try my best. When I first came to college I missed high school so much. It was always on my mind and because of that my first couple months weren't that great. But I got over it. I made friends and branched out and it soon became the best decision I could've made. So when you go to college, forget about high school and focus on your new experiences.
2. Don't go in with a negative mind.
Don't go into school thinking about how much work it'll be or how early you have to get up. Think about your new friends, new professors, new locations for some students. Think about all the fun you'll have and all of the first experiences. Think about positive things.
3. Do not go home every weekend.
I know that you have parents, and siblings, and girlfriends/boyfriends, but do not go home every weekend. You are paying to live on campus which means that you are paying for all the fun stuff that they do, but you're missing it. The movies and dances, you pay for those, but you'll never experience them. Don't go home every weekend, don't do it.
4. Choose a major based on your passions, not what will make you money.
I chose a major based on what will make me money and what will be needed when I graduate. Granted I do like my major, but it isn't my dream job. Do what you want. You want to fly planes? Do it. Do you want to be a doctor? Do it. Do whatever makes you happy.
