College degrees are respected because they are generally not easy to get. They demand effort and commitment and in the end only demonstrate that you have proven your potential to grow. This is something most secondary school graduates lack and why they are seldom considered for positions demanding a proven track record of learning and self discipline. Nobody who goes successfully into the workforce after graduation stagnates and much of what you will learn you will either never use or will be the foundation for future learning. Bear in mind that you will likely change your career path half a dozen times before you retire many years from now. Lesson is, focus on how to learn, not so much the material you are learning.
I graduated with an honours bachelor's degree in science 35 1/2 years ago. Less than half the people who started out with me in first year graduated with me after fourth. We called it educational Darwinism. The feeling of finally having completed my education was euphoric, like having a millstone removed from my shoulders. It is something for you to look forward to, but you're going to need to be strong and persevere, sometimes keep on going when you think you're going to drop.
I worried about the job market, too. There was a major recession in 1974-75 and jobs were scarce, like they are now. I took a logging job in northwestern Ontario. They made me a supervisor. It was a good job but tough and dangerous. Home only on weekends, blood sucking insects, baking heat and incredible cold but it opened the door for the next, better, job. And so on.
Advice from an old man whose been where you are: Get plenty of sleep, make sure you eat well, take it easy on the partying (but by all means party), exercise often, don't blow classes and put every ounce of your brain into it. After this, it gets easier and a lot more fun.
