I definitely 2nd what sahbi77 said.
Marketing is a cut throat game. If you're not on your toes, someone will take your job. We do it all of the time. It helps we've gotta couple of "gray hairs" on our team that worked for a reputable software/tech company in Seattle (hint hint). So we let them do all the selling for us, while us young guys hungry to make a million bucks, are busting our humps to be the best.
I'll let you in on a secret.
I scored in the top 5% in the state I went to high school in.
Because I was busy working on a t-shirt company, taking care of my G-ma, and a load of other life issues at 16 years old, I dropped out of high school in the 10th grade. That's right, didn't even finish high school.
One of my favorite quotes is from the movie Scarface: "Balls run this world" which translate to "having wit is all one needs to run the world, or their world".
An MBA doesn't mean squat in 2016, because there's always that guy (like me) that's a shark in the water and will get the results that take your client.
So you dont need college, but its good for making aquaintances and connections.
