I overheard someone say, “I’m gonna kill a few hours at a coffee shop”.

I pondered actually wanting to toss away time you have to be alive?  Tossing away a few hours in a day is like throwing out about $10 of $100 you have.  Why just throw away time or money?

On the other hand, the time you ENJOY wasting is not wasting time.  
It’s well spent.  If you like it, buy the coffee, stop and take the time to enjoy it.
