There are really only two ways to approach life - as victim or as gallant fighter - and you must decide if you want to act or react, deal your own cards or play with a stacked deck. And if you don't decide which way to play with life, it always plays with you.
The job of a friend is not to decide what should be done, not to run interference or pick up the slack. The job of a friend is to understand, and to supply energy and hope, and in doing so to keep those they value on their feet a little longer, so that they can fight another round and grow strong in themselves.
Friends are like windows through which you see out into the world and back into yourself. If you don't have friends you see much less than you otherwise might.
