I read a book way back when I was still hustling SaaS tech for a living about the virtue of setting a single objective.
The gist of the thing was to make one single task a priority and to give it full attention. This arrowheads the way forward for the rest of the day, making space for momentum to build around the project or goal.
Asking the question ‘what’s the one thing that will make most impact today’ helps to sift through the weeds of to do lists and competing priorities. In this way it’s possible to accomplish more than one thing since focus on a single task at any one time means the job gets done.
The satisfaction of completion is ample reward for sticking to ‘the one thing’ philosophy.
