You could be disabled. You could live on a deserted island all by yourself. You could be any race. You could be poor or rich. You can have bad circumstances. You can be an atheist or a religious person.
No matter what, you can always find something to be proud of. And if you don’t have something to be proud of, there’s the answer to at least a portion of the negativity that exists in your life. Find it and do it.
There really are no exceptions. It applies to everyone everywhere.
