I suppose I can offer up a differing perspective. Like you, I studied biology when I started college. Like you, I procrastinated my schoolwork. I went to college because that was the only option my parents ever encouraged. I had SAT scores in the 99th percentile, so it seemed the obvious choice. I certainly don't fault my parents for pushing me in that direction.
The only problem was that I didn't want to do it. I still don't. My heart was never in it. I didn't enjoy it. So I dropped out and joined the workforce working as a shipping clerk earning $9 an hour.
It turns out I just liked to work and liked to get paid. I was promoted shortly afterwards. Then I was promoted again, and again, and again. I won't share the whole story of how I got here, but I now have a career as a Business Analyst with over 10 years of experience in the field. I, college dropout, got selected for my present job over a field of 6 degree-holders, including one with an MBA and one with a computer science degree.
I have several friends who have achieved much success without going to college and we all have one thing in common. We got really good at something that pays well and is in high demand. We also spent a lot of time outside of our comfort zones to get there.
One of my best friends literally lived in a camper when I met him, having just put everything he had on the line to start his own business. He's now grown his business to nearly $1M per year in revenue, and he's only 33. He barely finished high school. Now he barely goes to work, spending most of his time playing with his toys in the woods and lakes of Maine.
I'm not encouraging you to drop out and I'm not trying to give you the idea that most college drop-outs achieve six figure incomes in their thirties. Most don't. My results are probably not typical and neither are my friend's. That said, I didn't just get lucky, and neither did he. I busted my ass, took risks and made the most of just about every opportunity that I recognized. Anyone can do this, whether you hold an advanced degree or not.
I was NOT cut out for college, even though I had SAT scores and high school achievements that would have gotten me into just about any school in the country. I was not college material because I didn't have the right attitude, academic work ethic or DESIRE to pursue a college education. I still don't.
Just be warned that doors will not open easy for you when you are young and uneducated. You'll need to pry those motherfuckers open, and some won't open at all no matter what you do.
My advice is to fix your attitude and make the most of the opportunity that is in front of you right now. Or you could just move to N. Dakota and learn how to weld. Truck drivers do well out there too.
