Without appreciation and gratitude, it is easy to fall into small, petty ways of thinking—a poverty of mind worse than any material poverty.

Wherever you look, you see only shortages: not enough time, not enough patience, not enough money.

If this goes far enough, you feel defeated by the sense that we can never accomplish anything of value.

The quicksand of failure forms beneath your feet and you sink into it.
