I constantly use these.

For anything you want that you don’t have, answer three questions:

1. Is it possible?
2. Am I capable?
3. Am I willing?

How many things you want are within your capability and outside your willingness? If it’s possible and you’re capable there’s only one question that matters. And one answer. Whatever it is . . . declare it and own it.

Discipline is the shortcut. Do the work.
