I've been listening to a lot of Bill Gates on TV, somewhat coincidentally.
I need to remember a few things he says.
1) He makes products that he would like to use.
2) He believes that software is magical and powerful, and the capabilities of what you can build with software keep increasing.
3) He believes that the so-called risk he took in dropping out of Harvard, was actually a very low risk. Right time, right place, sniff it out.
