When considering a new project, it might help to make three lists:
A list of everything that has to be true for this to be a good project (things you can look up, research or otherwise prove).
A list of all the skills you don’t have that would be important for this project to work (things you can learn, or hire).
And a list of everything you’re afraid of, or things that are essential and that are out of your control….
On paper, it's a lot easier to find the real truth.
