"Well done," is perhaps the most simple and effective of compliments. In addition to a "well" symbolising a source of truth and goodness that nurtures society, "done" suggests that you have reached a point of accomplishment where a rest has been earned. Victories deserve celebrations, even if they are small.
Well done; you've done well. You were tasked with the impossible, we all were, and we came home with victory. We need to have real cognisance of the suffering our side took on, those reflections will feed into the risk assessments for future missions. We have secured many gains, some already and many to come as the good seeds begin to flourish and grow. Whatever you do now is up to you. Enjoy the rest of your time here and we will see you when you are ready to cross the rainbow bridge. Sending love.
Well done, take a bow, but your party dress on go have some fun. That's an order, Commander.
They call it impossible until it is done, then see it as obvious and simple. You did the impossible, child, that there is no earthly applause is expected. The heavens, however, are in raptures at the strength of your heart.
