It’s difficult to be grateful for life’s blessings and achievements if your measuring stick is the person at the top.
This is why high achievers often fail to appreciate what they have. The same quality that makes them successful also causes them to be ungrateful: the ability to set their sights impossibly high and accept nothing short of success.
If you want to be successful and unhappy, always compare yourself to the very best. The secret to being grateful is to compare yourself to those with less, or, even better, to the person you were yesterday.
