a little better than nothing

I am too tired and frustrated. Long weekend, rainy, and I have to read all day long. With very low efficiency, I feel I just want to give up the whole day and got mad at myself.
But I tried to tell myself: being mad at yourself won't help. You are just wasting more time. What you need to do is relax and back up a little bit. Don't push yourself too hard. A little progress is better than nothing. No matter how difficult it is, little by little, you will finish it. You do only have limited time, that is why you became frustrated, but frustration won't help. You have to figure out what is more important and have to learn to give up. Chosing things out and giving up something else is always a difficult thing to do but it also always the thing we need to do. Wise choice will make things different. So, pick one and keep going.
Relax a little. Sit back and deep breath. Open the book, start it over.
