Life time is quantified in years. Years are made up of months, which are made up of weeks and further broken down into days, hours, minutes and ultimately second, or even microseconds!
Time is life!
Who is spending your life? Life is precious, as can be seen when someone is bleeding away and fears escalate of life ebbing with imminent death. Life quantified in time therefore implies ineffective use of time is ineffective use of life!
Every life matters, guard your moments, guard your time, guard your life from being misspent! You only live ONCE!
