Optimism is a state of mind?

What is there to be optimistic about?

With all of the negativity in the world, sometimes I wonder. The economy is in the tank, my business is in there with it, and my grandmother can't remember how to use a phone. It's exhausting.

But then... then I come home. To frantically happy cries of "MOMMMMMYYYYY'S HOME!!!" as my children rush to greet me. I breathe in their smell as I pick them up and wrap my arms around them.

That. That particular smell of little boy, sweat, and a fun day of play for them.

That is what there is to be optimistic about.
