We could ask – when is it a good time to start on this new project?
It turns out that there really isn’t a “good time” to start anything. And, we’re never completely ready. Barring outrageous luck, we’ll be moving against the current and will need to learn a lot more than what we imagined.
The way forward, then, is to wait till just before we feel ready. Then, say “This might not work.. and that’s okay” to ourselves and take the leap of faith.
Any time we choose to start is a good time.

Glad it resonated, Mike! :-)
