The kind of job where you come in and work 9 to 5, and where someone tells you what to do all day is becoming scarcer and scarcer.

The kind of job where you have to hustle and hustle and where you're not sure whether you will have enough clients next month, where you have less job security, is becoming much more common.

I prefer to be busy all day long, and when you work for someone else, you're not busy enough.

Knowing how to keep someone motivated and how to keep a connection are skills humans have learned and evolved over hundreds of thousands of years. A robot can't figure out whether you can do one more push-up, or how to motivate you to actually do it.

When someone is impatient and says, 'I haven't got all day,' I always wonder, How can that be? How can you not have all day?

We're rapidly entering a world where everything can be monitored and measured. But the big problem is going to be the ability of humans to use, analyze and make sense of the data.
