"What drives me."

I'm 51. A few times in SF I was asked, how do you keep your drive? My father is your age and he is stagnating.

I started work at 21. I hope to be less than half way through my career. There is a huge amount for me to achieve. It's easy to be driven.

I have learnt more in the last 5 years than in any others. I will keep doing that.
