I work as a consultant, which is to say I'm in sales. I take C-level meetings with mid to large sized businesses on a weekly basis. One thing I do, which could be applied to most any undertaking is a self critique. When I leave a meeting I will intentionally reflect on the things I did well as well as the things I could improve upon. If things went well I ask myself "why" did they go well. I access how much of the talking I did, did I ask the right questions, why were they the right questions etc.

I've been through thousands of hours of training over the years to become better at my chosen profession. This actually ties in nicely to the conversation b_b, geneusutwerk and AlderaanDuran are having here. My college education has almost nothing to do with my successes. Nor has anyone in my organization ever asked me where I went to school. They do ask me if I hit my growth metrics for the month/year etc. For the most part in business, nobody cares where you went to school but they do care whether or not you are capable. There's a saying in sales, "You're as good as your numbers". -The numbers don't lie... and they certainly don't care where you went to school.
