It's frustrating to get lost in the tyrannical distraction of NOW. Quickly one is lost to simple, mindless reaction, weaving to and fro, accomplishing little to nothing; even though the day was full, laden with busy. The result of losing focus.
When priorities get lost by attending too much to the blizzard of demand, emptiness wins. We're active, yet no progress made since "what matters" was left undone.
One must slow down, consider the value of each task before you act. At least get the priority work done first, the stuff that moves you forward. Even better, more powerful; learn the value of "no". Decline to take energy away from your priorities. Doing more by doing less. Focus your energy for energy isn't limitless.
