Dealing with the feelings I get when I change my plans.

Do you ever have the feeling that you wish you had paid better attention in school? I have that feeling regularly.
In the drawing course I did early last year I was advised to practice hashing and cross hashing but since I thought I wouldn’t need it I didn’t listen. So now I’ve reached the point that I have to learn the technique I don’t know how I’m supposed to go about it and what my goals should be.

But I also have the feeling that this isn’t the real problem. If I only wanted to know how I should go about practicing hashing I could look it up on the Internet or find a book about it.
I won’t.
I won’t because this is a feeling I have quite often. Usually after I had to change my plans. Which has me suspecting that this has something to do with being autistic. I just need a few days to get used to the fact that I’m going to do a lot of practicing and blog about practicing.

If I still have this feeling in a few days I still can find information on the technique.
