"It is possible to be happy and joyful most of the time.
You just have to look at little children and see their natural joy.
You may say that little children are free
and don’t have anything to worry about, but you are free too!
You are free to choose worry or to choose joy,
and whatever you choose will attract exactly that.
Worry attracts more worry. Joy attracts more joy.”
it might be a good thing to try.
