As clear as it looks, it's just not easy to follow. At my age right now, i tried to do the best to make everyone happy. And most of the time my own expense. And then one day you found happiness in an instance, you smile more, you laugh more and you wake up everyday a little lighter. Then suddenly BAM! reality sets in and you have to let go of that "happiness" to make everyone happy again.
I pray to God that He will bless me with contentment. To be contented with what I have now, to be happy at where I am now. I choose to be sad now and pick myself up and fight to achieve contentment and finally to be happy too. As other people say "Let go, Let God".
