Work, Family, Health, Friends and Spirit
Posted by Abid on December 17th, 2009
Imagin life as game in which you are juggling some five balls in the air. You name them – Work, Family, Health, Friends and Spiri and you are keeping all of these in the Air.
You will soon understand that work is a rubber ball. If you drop it, it will bounce back.
But the other four balls – Family, Health, Friends, and spirit – are made of glass. If you drop one of these; they will be irrevocably scuffed, marked, nicked, damaged or even shattered. They will never be the same. You must understand that and strive for it.
WORK EFFICIENTLY DURING OFFICE HOURS AND LEAVE ON TIME. GIVE THE REQUIRED TIME TO YOUR FAMILY, FRIENDS AND HAVE PROPER REST.
