Dress better than you
Drive a bigger car
Go out to dine more frequently
Travel abroad more than you
Has more material wealth than you
See, you look at the others who motivate and inspire you and draw your simple admiration but you stop wishing that you too live like them and stopping exactly at that point!
If you stop yourself at just the point of wishing, you end of being in a state of envy. And, there! You will never live to experience the same when you are in that state.
But, if you appreciate others' better and richer life, it is like saying to the Universe, "More of that please".
