This may sound odd, but when I am feeling down and/or worried about the future I think how things are or may be versus the how bad things are for other people.
As in...I am not - homeless, starving, in prison, disfigured, disabled, destitute, dying or a myriad of other things. And the more I work on me, the better person I become and I am the only person I know I will be around for the rest of my life.
Of course, I want to save my family, but what is the worst case scenario? Something that 50% of all married people go through. We all know divorced people who are leading healthy, happy lives.
