The days of you having a different image for your work friends or co-workers and for the other people you know are probably coming to an end pretty quickly. Having two identities for yourself is an example of a lack of integrity.

If you actually do something you love it's a lot easier and takes on a lot more purpose.

Companies face a handful of different risks, whether it is competitors or different market environments. But I think that people focus way too much on competitors and not enough on their own execution.

My friends are people who like building cool stuff. We always have this joke about people who want to just start companies without making something valuable. There's a lot of that in Silicon Valley.
