Getting used to busy days

I used to complain a lot about my Weds. since they are pretty busy for me and I teach from 1:30-8:30. I would be super exhausted and I wouldn't even have enough strength to walk home. Today was pretty easy since I had two unit quizzes in my classes but even after work, I wasn't super tired and I even graded one set of quizzes. I stayed a little bit longer at work to grade and I'm not so tired. I'm proud that I have built some stamina, it's about time since I have been teaching for about 9 months lol
