Quality Over Quantity
You should relish missing out on the non-essential, or the Joy Of Missing Out (JOMO).
I took note of an idea from Humble the Poet a few years ago in an interview where he suggested measuring success by the opportunities we get rather than the ones that yield result.
Take pride in the variety of opportunities life gives you—but be discerning in the responsibilities you accept and the tasks you undertake.
One of the great cons of modern life is the assumption that all tasks are of equal value.
The issue with busy-ness is that the importance of each individual task is averaged out and we replace output with the feeling of effort.
