One of my investors told me after a great year of sales, "Now the trick is to maintain momentum."
Jim Collins devotes an entire crucial chapter to the Flywheel concept (slow, steady momentum) in Good to Great.
A leader's job is to create and maintain momentum. Nothing else is as important as this.
Get people, sales, marketing, product development, conversations, and customers all pointed in the same direction.
Then get them moving toward that direction.
Then keep moving them until they reach a goal.
That is your job.
