College vs University for internet marketing? (high school even?)

Just wanted to quickly try to test a theory on here.

I know a lot of people that are starting out in internet marketing struggle with analysis paralysis an especially they over-analyze a lot of things and try to come up with a perfect plan instead of focusing on execution and testing strategies. Why is it that some people seem to have no problem engaging in the hypothesis testing process whereas other people really seem to struggle when it comes to formulating a plan and sticking to it?

I have a theory that people who are more academically inclined take a more research-oriented approach to their business - this is how I used to be. I would find one source of information, maybe a forum or a course or some other material, and I would take notes and learn all the information and how the processes worked in order to execute that, but I would never do the actual work to make it happen. If I did do the work, I wanted to see results right away and I was never willing to put in a lot of up front effort to make things work for me.

In addition, I would find other sources that said something slightly different and I would try to find correlations between the source material so I could determine what "really" worked and what seemed like it was just a scam or whatever. This was a terrible approach!

I'm wondering if you can tell me your education experience and what it was like when you first started out. Were you scared to fail? Did you have analysis paralysis? How did you view failures and the testing process and how comfortable were you with the fact that your work didn't always get you immediate results? We live in an instantaneous gratification society - did you have to change your attitude to get success?

Any input would be well received.
