I guess I learned that lesson the hard way.
In good news, I had a wonderful day with many great moments. I took today off from my GA job to have a study day with one of my classmates, and we were both productive! I understood most of statistics lab, and I really enjoyed my Foundations class this evening. After class, I came home, took off my pants, and cooked cheeseburgers before putting (or attempting to put) the finishing touches on my statistics homework. Now it’s nearly midnight, and I’m wondering what I am doing awake at nearly midnight yet again. Maybe tomorrow will be different.
