Epictetus (AD 55-135) the Greek sage and Stoic philosopher observed:

“He is a wise man who does not grieve for the things which he has not, but rejoices for those which he has.”

If you are truly grateful for what you already have, will that stop you from seeking and obtaining more?  Is your role in life to be one who is always seeking?  Why not try rejoicing for a change.  What is the point of acquiring riches if you never take the time to enjoy them?
