This translates to "If you are sad, act!" The reason I am posting this, at great risk of being called a geek, is out of my love for all of you. I felt really rotten this morning, and then I buckled down and got a bunch of work done. I cannot tell you how much better I feel after only an hour of concerted effort on a task I was really dreading.
So these are my words of wisdom to you on this Monday. If you are sad, do something constructive, and preferably something you really don't feel like doing. The entire Klingon homeworld can't be wrong.
