And doesn't momentum, being a vector quantity, already have a direction?

- sokoloff 3y agoYes, but I read directionality to include the thoughtful/intentional choice of a given direction, making the pairing of "you should be thoughtful about your choice of direction" (directionality) and "you should also commit energy to ensure you actually make progress in that direction" (momentum).
