Grit by Angela Duckworthby Parker on TwosGrit is not just working incredibly hard. That's only part of it. There are no shortcuts to excellence, developing real expertise, figuring out really hard problems. It all takes time. Longer than most people imagine. Then you know you've got to apply those skills to produce goods or services that are valuable to people. Rome wasn't built in a day. Grit is about working on something you care about so much that you're willing to stay loyal to it.It's doing what you love, but not just falling in love, staying in love.
