There are different types of joy. You cannot compare the joy on Christmas morning as a mere child as the the you feel getting a good mark on your report card. You also can’t compare getting a raise to when you got your first pet. It’s just not the same. You caannot say when the most happiest tiome of your life is, because every other moment, cannot be compared. Would you have enjoyed that raise as much if you were still that child on Christmas morning? No, you wouldn’t even understand what it was! Levels and types of joy come from moments shared, hard work being paid off and something unexpected occuring.
Life is filled with tiny bits of joy to keep us going, and great moments of joy to look back on and smile. Sometimes we don’t appreciate things at the present moment that you will remember and learn from later on. Never doubt a moment in your life, either good or bad, because even it could bring you joy, directly or indirectly, later on.
So why waste Joy by comparing it, and judging it on the past, present or future?
