Leave a piece of paper early morning at the rise of sun and come back to it at sunset. The paper remains still.
For few moments the next day, go to it with a piece of magnifying glass.
Now the paper burns because of focus.
Having your goals is like Day 1. Kept in the sun. Left to external situations.
Day 2 is for the obsessed ones. They see nothing and no one other than their goals.
They do not care about what their neighbours think, have zero interest in new season of GoT, forget when did they last check their social media, and have total unavailability of time for thinking about the past.
Just them and their goals and their few most important people. Nothing else matters. That is when the paper burns because of focus.
