A joke: Philosophy of life
Pay attention to the things that are critical to your happiness. Play with your children. Take time to get medical check-ups. Take your partner out dancing. There will always be time to go to work, clean the house, give a dinner party and fix the disposal. Take care of the rocks first - the things that really matter. Set your priorities. The rest is just sand.
But then... A student then took the jar which the other students and the professor agreed was full, and proceeded to pour in a glass of beer. Of course the beer filled the remaining spaces within the jar making the jar truly full.
The moral of this tale is that no matter how full your life is, there is always room for BEER.
