To be authentic is to have candor but deliver it carefully. You should be helpful to your team and customers. Have strong beliefs that are loosely held, where you are confident but also OK to be challenged on a belief.
To have belief is to be passionately determined. That determination should not be knocked when things get difficult. Have the grit to see if through.
Iterate with continuous improvement. Embrace simplicity. Be frugal.
You root for the underdog. You might be an outsider, but that's ok, because we want people to disrupt that status quo. Sometimes making a hack is the best choice.
