It is what we do to learn a new skill and master it. Then, we repeat the same thing[-, and initially, there is some failure, but with time there is a progression towards what appears to be perfection.
That same principle applies if we seek to optimize time. Repeating the same activities, behaviors, and actions with frequency and consistency becomes the most straightforward path to improving productivity and effectiveness.
While we program or set machines to operate with precision by performing functions repeatedly at set times, we equally would benefit from these set routines. Knowing what comes next without little thought, and creating a logical sequence of activities, improve our focus and efficiency.
