Strangely, it's not an experience I'd ever trade.
I learnt more about the mechanics of human nature in those two and a half years than any time prior or since.
However, enough was eventually enough, and it was time to graduate from the school of hard-knocks. Time to return to that other school, the one of stressful late nights, exams, and red pen. Postgrad school.
It's funny how periods so tormenting to endure can be viewed with such fondness in retrospect. The two years spent completing my Psych Master's is one such period. In no small part, I'm sure, because it's where I met my now gorgeous wife. (I don't mean she's just now become gorgeous, she was always gorgeous! But now she's my wife too.)
On completion, I was a registered psychologist who had an appetite for marketing and sales. I was also patently unemployable, fired from every job I'd ever had. Going into business for myself seemed more and more like the only viable path. And if that was to be the case, well, I better get another piece of paper!
So, upon graduating from my Psych Master's, I jumped straight into an MBA degree. Lucky for me, my prior academic history was extensive enough that I could finish the MBA inside 12 months.
