I know old people people like myself say this to college/high schoolers all the time. But appreciate that summer vacation while you've still got it. Cause one day you're gonna be an old man like me, ok I'm 28, but still. I mean even if you're still having to work a part time job. It still beats going the full year without summer vacations anymore.
And you know, while I'm giving advice. When figuring out what you'e gonna do with your life, and I know you've heard this before, pick a job that you're going to enjoy. Don't think about what job will make you the most money, or what is the easiest job you can possibly have. Think about what it is that you like to do, and then get a career doing it. Because if you have to get up everyday and spend 8-11 hours at a job that you don't love doing, it will get old fast.
