This sentence means that when we set a goal or want to do something, we should stop wandering. As long as what we set is correct, we should strive for it and realize it. If you keep wandering back and forth like this, there will be no result, and any ideal is impossible to realize, so don't wander any more. Therefore, when a boy takes this sentence as his signature, it means that he reminds himself that he must be a firm-minded person, dare to pursue, and never wander in the same place. This should be one of his mottos, so he will use it as his signboard.
