If you wait until you’re in the right mood to put the bins out you might find yourself waking to the sound of the garbage truck as you swear under your breath and your partner asks “did you remember to put the bins out last night?”
Of course you didn’t remember, you were too busy waiting to be in the right mood.
The same is true with having a difficult conversation, starting (or quitting) a project or going for a run.
It’s unlikely you’ll be in the right mood before taking action, instead we can choose to intentionally take action and then allow the mood to follow.
Put another way: waiting for the right mood is a form of hiding.
See this interview with Rich Roll for more on this idea.
