How do you determine what you passionately want to do? I’ll share my own experience. Before I left Microsoft, I took out a piece of paper, and listed those moments in my life I loved most. I tried to identify patterns. With that information, and a bit of research about various career options, I picked something which I thought would allow me to do what made me most happy. I also paid close attention, using the same method, to things I didn’t like to do, and worked hard to eliminate those things from my life.
