You try a lot of things and you don't know what the hell you're doing. If you're actually inventing something you shouldn't know what you're doing.

Working on the right thing is probably more important than working hard.

A lot is gained through experience, but experience teaches some and not others. Effectiveness and excellence, whether or not they were attained by simply having the knack or through the school of hard knocks, is really what you want to reward.

Inspiration is really all around us. I pay attention to a lot of different fields. I stay up on current events. I go to community meetings to see what concerns the people in my neighborhood. Paying attention to social interactions offline really inform interactions online. The real world is a bottomless source of inspiration for what you can build.

Being open and observant of people and the world around you is really important. People have the same desires and needs online as they do offline. The way that people are stays constant. You can change the format, make it easier for them to communicate or use photos instead of words but human necessities never change.

If the business were a play, Act One is: Woohoo, bright and bushy-tailed. We're going to make something great! Act Two is: We're six months behind on back-end development. We're trying to raise venture capital. We're trying to figure out what furniture we should sell to make payroll.

It's the building of things that makes you happy. You have to enjoy the process whether you succeed or fail.

No successful company has had ever been the product of just one person.
