How to keep yourself happy

Let us think about it in a simple way, why children are always happy? because they don't think of more than their simple needs, they get angry some times but in a short time they forget all about it !! they feel sad for things they missed or lost, but in no time they turn to be happy with other things they found near and available.
Children use their imagination to create what keeps them in a good mood, they feel happy with the nature surrounding them, they never lose their interest of asking, why ? where? or what ? all thoes kind of questions that keep them hungry for knowing all what around them , they never stop asking.
After all the years i left behind and despite all troubles i got through ( and they are much !) I still have my heart pure from hate and far from jealousy. I don't expect much from life, and feel happy with everything available ! I look to the sky and say wow!! what a beauty!! Guess what ? I still keep a child in a corner inside me , and i feel proud of it and never hide it, for that, i suffer with people, and like to talk about it and hear from you.
