Think about the metric by which your life will be judged, and make a resolution to live every day so that in the end, your life will be judged a success.

An innovation will get traction only if it helps people get something that they're already doing in their lives done better.

This is one of the innovator’s dilemmas: Blindly following the maxim that good managers should keep close to their customers can sometimes be a fatal mistake.

When the functionality of a product or service overshoots what customers can use, it changes the way companies have to compete. When the product isn't yet good enough, the way you compete is by making better products. In order to make better products, the architecture of the product has to be interdependent and proprietary in character.

And if your attitude is that only smarter people have something to teach you, your learning opportunities will be very limited. ... When we see people acting in an abusive, arrogant, or demeaning manner toward others, their behavior almost always is a symptom of their lack of self-esteem. They need to put someone else down to feel good about themselves.

I've concluded that the metric by which God will assess my life isn't dollars but the individual people whose lives I've touched.

What you need is a fundamental humility - the belief that you can learn from anyone.
