I've learned to question success a lot more than failure.

When we get our sense of self from only one place, when something goes wrong and the inevitable happens, it can crush you emotionally, spiritually and physically. So it’s important not to believe you are defined by one place, one relationship or one thing, and to find ways to keep your sense of self strong.

Focus on things that are small enough to change, but big enough to matter

Success is mostly driven by how badly you want something and how well you partner with other great people. It has to do with how hungry you are.
