HAPPINESS.
At best, they will achieve an absence of unhappiness. But that's not the same thing as actual happiness.
I, on the other hand, will be achieving a great deal of happiness on the three day weekend that commences tomorrow. The weather will be superb. I will go on bike rides. I will enjoy overpriced lattes. I will have band practice. I will do yard work (in full transparency, I will not be happy about the yard work, per se, but I will be happy with how the yard looks when I am done).
Have a great weekend!
