We create it

only things that matter in life are what we choose to matter.

The only things that make us angry are what we choose to make us angty.

The only things that make us sad in life are what we choose to make us sad.

The only things that bother us in life are what we choose to let us bother us.

It is all a choice within us as to how we react, see or experience now. We create our life.
