    Communicating honest feedback is very hard. I now give very blunt advice because I realized all of the most impactful advice I’ve gotten in my career has been blunt. Blunt friends/coworkers/advisors are the heroes of my life story.

    I encourage everyone in the startup community to learn about and support anti-police brutality efforts in Nigeria. We are one global startup community and we support one another.

    8 out of the 9 top stories on NYTimes are negative right now. Google News even worse…. I know there are serious problems in the world but I wonder if it’s healthy for the billion+ people online to read largely negative news about the world every day…
