From James Clear’s newsletter:
You only need to know the direction, not the destination.
The direction is enough to make the next choice.
How many times have I let “I don’t know exactly what I want!” prevent me from taking any action? Too many. But I usually knew what I wanted more or less of. I knew the direction I wanted to go even though I didn’t know where I wanted to end up, and that’s enough to do something about it.
Remember folks: plan the sprint, not the project.
