You can tell how big a person is by what it takes to discourage him (Nubiagroup.blogspot).
Some people seem to be in a bad mood most of the time. They are discouraged almost to the point of depression. And when you discover what it is that has discouraged them, you may find it is only a very small issue. How encouraging it is to meet people who are rarely despondent because they think positively and don’t let the little things slow them down.
Have I not commanded you? Be strong and courageous. Do not be afraid; do not be discouraged, for the Lord your God will be with you wherever you go (Joshua 1:9).
