You don't want to negotiate the price of simple things you buy every day.
Obsess about customers, not competitors.
I try to spend my time on areas that I think are important for the future, and where I think I can add value.
The death knell for any enterprise is to glorify the past -- no matter how good it was.
If you do build a great experience, customers tell each other about that. Word of mouth is very powerful.
My view is there's no bad time to innovate.
