There is a big difference between those that “want” and “have”. those of us that want a job don’t have the opportunity get one! Those of us the have a job don’t want it!
So the moral of this proverb is Have less and be happy than those who want more and have less!
Well maybe it might be different in your case but I was just thinking about this when I was walking down the road minding my own business and was approached by two angels! One asked me for bus fair since he was so far away from his home! (imagine that!) and the other needed bus fare to get home. Neither one of them looked any different but I gave them both what I had in my pocket and continued to walk and realized that I have less now and felt better and those that want more, have what they need just to get home!
