Learn From A Teacup
Take a teacup from the cabinet. Pour some hot tea into it. You will find that it can hold a certain amount of tea and no more. You can try to pour in all you wish but the teacup will only take so much. The rest will spill on the table and hands and you will get burned. Do not waste tea by taking what you cannot drink. The teacup is satisfied at a certain amount. Learn to be satisfied with less. By having less you will have more. Be like the teacup that knows when to say when.
