My advice is flip a coin. If you regret the way it landed, then go with your gut.
Start-ups don't die, they commit suicide.
Surround yourself with people who do what you want to do, and eventually you’ll wake up to find yourself doing the same.
I try to work the hardest I can without burning myself out.
I try to keep the meetings small, especially when we're doing product design.
You need to just get started. If you never get started, you'll never be successful.
