Do the work.
It might not work.
Doing the work guarantees you an outcome, it might not be the one you wanted or expected. But perhaps it is the one you needed.
And yes, not doing the work also guarantees you an outcome too. The one you currently have. However, you wouldn’t be dreaming of, thinking about something different, a change if you were happy with the outcome you currently have.
Yes it is scary. Yes it might not work. And yes, that’s ok.
Do it anyway.
The choice is up to us.
