Which of the four are getting in the way?
Seth Godin

1. You don’t know what to do
2. You don’t know how to do it
3. You don’t have the authority or the resources to do it
4. You’re afraid

Once you figure out what’s getting in the way, it’s far easier to find the answer (or decide to work on a different problem).

Stuck is a state of mind, and it’s curable.
