Alex, I understand your dilemma. In high school, I started a computer networking and repair company and was making $60 an hour making my own schedule and being the boss (of me). For a time, I considered not going to college because I too thought I didn't need it. Ultimately, I felt I needed to go to conform to what was then, 2006, a clear cut path in life that I must graduate high school, to go to college, to be successful in life. The world was a slightly different place back then. Facebook was barely started, there was no Uber, there was no AirBnB, etc.
When the '08 crises hit, and banks stopped lending money, and the economy completely shut down, I felt fairly grateful to be in school and switching my major to accounting which guaranteed me, literally, a job out of college. I've since moved on from that, but I still have my CPA license which serves me well in many capacities.
The point of sharing all that is that we never know what is ahead in life. We don't know what the economy will be like, or what jobs will be available, or what industries will be revolutionized through technology. There are very few people I talk to who say they regret their time in college. College is a maturing process and you can make some truly wonderful relationships. You can also waste 4 years of your life and a lot of money if you don't take the opportunity seriously. Another thing to consider, it will never be easier to attend college than it is when you're younger. You tend not to have family responsibilities and as you get older, your desire to sit still and learn diminishes even further - particularly in a heavily structured setting like college.
All that being said, it sounds like you have a definite vision for your life. There are MANY successful people who didn't attend college or who dropped out. Typically because an amazing opportunity came their way. If you're seriously considering not going to college, you need to obtain an education in what you are interested in by finding a mentor and busting your butt. There are plenty of people out there who are looking for someone to hustle. I literally heard someone ask to find help finding a mentee yesterday in Austin for real estate purposes. You won't need to go to college to be a successful real estate developer or investor. However, you may find that you need the job that college can offer in order to obtain the capital needed (not necessary if you're a good salesman and can put other people's money to work).
I've never had someone ask me whether or not my college degree justified or allowed me to do business with them on the real estate side of things.
