There are days I need to remind myself of the following quote:
“One way or another, every setback proves later to have been a step towards victory. Each defeat brings another host of followers, indeed, right from the ranks of the foes of yesterday…. After every failure it is necessary to examine yourself and ask, “Look here, perhaps you are wrong?” If you are wrong, get off the rostrum and shut up. But if you are right, do not believe your eyes: that defeat is no defeat. ‘No’ is no answer. Wait an hour and start over again from the beginning”
