An Elephant Never Forgets. Does that mean he is never happy?

Why is it so easy to forget things? Often I find myself forgetting some of the most important things to me. Like writing my weekly analytical essay, I often forget to do it until it is almost too late. Or doing my jobs from my family’s “Crappy Happy Helper Chart”. For some reason these important things that bring me so much joy often slip my mind.
I have given it some thoughts and have come to the conclusion that these things make me too happy. Just the thought of writing my analytical essay for the week brings me such euphoria that it drives all other thoughts and feelings from my mind. I end up standing/sitting there with an unexplainable happiness inside having no idea where the feeling came from. The same goes for my “Crappy Happy Helper” jobs. I think about doing them, the happiness comes, and I forget about them. So if you want me to remember something, make sure the thought of it doesn’t fill me with too much joy.
