I seldom count the minutes I spend shaving because I consider them as precious. If I waste the moments counting I am losing moments enjoying them. Here's a few words of wisdom about time.
"If we take care of the moments, the years will take care of themselves." Maria Edgeworth
"There are two days in my calendar: This day and that Day." Martin Luther
Now listen, you who say, “Today or tomorrow we will go to this or that city, spend a year there, carry on business and make money.” Why, you do not even know what will happen tomorrow. What is your life? You are a mist that appears for a little while and then vanishes." James 4: 13-14
So don't waste your time worrying about what moments are spent on the things that you love. Rather, cherish them and count them as a gift...shaving while you cherish.
