This interesting paradox came to me this morning.
Every day, most of us are so regimented to the 24 hours that the clock gives us, that time rules our life (literally minute by minute). Alarm clocks, deadlines, school bells, timetables, bed time. Yet the decisions we make every day are often based on a sense of immortality in this life, that we have all the time in the world. We therefore choose to do things that are really unimportant and often a waste of our precious non-renewable resource.
If you find yourself doing something today that would feel really unimportant if you were to look back at it from your deathbed, try doing something else.
