It's easy to feel like a failure when you realize you've made no progress on a homework problem. You've exhausted every resource to find the solution, yet the solution is still unknown.
I spent over an hour on a single homework problem, and I'm still not sure how I arrived at my answer.
So now it's 11:30pm. I have work tomorrow at 7:30am. And all I can think about it my homework and how I was unable to solve the answers, when I'm sure the other kids in the class solved it with ease. I hate that feeling.
Dear SleepJuice (wine): Please kick in soon, I need to sleep.
