I feel like I'm really dumb occasionally. Mostly because I feel like I forget math related things to easily. I'm better than I use to be by good bit, but I still feel like I'm refreshing my memory more than I should be. Also, I still haven't gotten an intuition. Like for example there is this problem "there is a rope that is 140 feet long. It is cut up into 3 pieces. The longest piece is 5x the other two. How long is the longest piece?" I got 20 but I think it is wrong and it took me forever. I should be able to do this stuff instantly. I just don't feel smart. It's very annoying. I don't know what to do. I want to be better. I feel like I worker harder and care more but get less done. It makes me hate myself a bit really. What can I do to get better/smarter? Thanks.
