Good idea or distraction?

How can I tell if something is a good new idea v. a fun distraction?

Context – I have been planning (but also procrastinating) for a launch for my membership program (established program running for 2 years, but with total members far below where I’d like). I had an idea this morning of a different way to launch, that feels more aligned and I’m more excited compared to the challenge launch I have been planning for.

Is there a way to tell if I should scratch the challenge launch and go for this, or if this is just my brain tricking me into more procrastination?
