There is no one as strong as a person whose heart is always filled with gratitude meaning. True strength is not how much you can lift or how far you can throw, true strength comes from within and can not be bought or trained for. When you have a heart that is always filled with gratitude and a positive outlook on life then you are stronger than the biggest bodybuilder or the most successful Olympic athlete. When life takes a bad turn and things get tough you will always find something in this world to be grateful for no matter how grim the outlook may be. Gratitude will help you find the bright spot in any bad situation, and keep you strong when it seems like life is trying to beat you into submission. Without gratitude all you will see is the negative side of life and this will always bring you down.
