The most wasted of all days is the one which you have not laughed.
Try harder to keep things in perspective and recognize what really matters. This will allow you not to take life so seriously and to find time to laugh with those you care about the most.
Count it all joy, my brothers, when you meet trials of various kinds, for you know that the testing of your faith produces steadfastness. And let steadfastness have its full effect, that you may be perfect and complete, lacking in nothing.
