What are the lasting ways in which business school changes you, beyond the knowledge that you glean? For me, business school made me far more aware of time than I had been previously in my life.
At business school, there were always far many more activities than was time to do them. Having to pick and choose, and seeing the outcomes from these choices, really made me conscious of the value of time and how the investment of time we make shifts the directions of our lives.
In my particular case, I choose to spend time on starting a company while I was at school, rather than recruiting for a job. Both are significant undertakings. Just starting a company is itself hard to do. It is even harder to do while recruiting.
