Dude, I would not drop out of college.
Thats just me though. I value education because it is more than just a piece of paper you get.
It is the ambition the discipline, it is aiming high, and your mind is like any other muscle. you need to exercise it for it to grow bigger and stronger.
Hell I am crushing it in my market BECAUSE I am a NASA caliber robotics scientist.
I became a master at SEO because I see numbers. I see patterns. I understand and see the reasons for something before I even know myself why it is.
I am not saying you NEED to go to school, but why drop out? Not only is it a waste, you are training your mind that giving up is an option.
You are young, and you have the energy to do both at the same time. Ask yourself if it is not just lazyness or a shortcut you are after, BECAUSE know this.
Most people fail doing REI. MOST as in 90%+
So many reasons why you shouldn't drop out of college.. but then a gain.. I am biased.
I am extremely educated....
so lets wait for the others before you take my advise too seriously.
