Many many external circumstances are outside of your control, but will affect the outcome, and you have to be OK with that.

Start-ups don't die, they commit suicide.

I try to keep the meetings small, especially when we're doing product design.

My entire career has been pivoting from company to company. Some people call it lack of planning or direction, I call it flexibility and good improvisational skills.

I try to work the hardest I can without burning myself out.

My advice is flip a coin. If you regret the way it landed, then go with your gut.
