You can always be and feel happy, because always there are good things in our lives which are positive. View it on that side, I would tell you.
Moreover, if you’re Christian you can be happy, because you’re a child of God (!).
As well we’ve been created as image and likeness of God.
If you aren’t Christian, you also are called to live as children of God, of course!
I say these positive things today because life brings sorrows with itself, and saying positive stuff might help us all on regular days. / Photo from: www craized com
