not as smart as i thought

i’m finding that my AI homework is a lot more difficult than i expected. it really reminds me how weak my brain has become from lack of exercise. i’m also very undisciplined, but ignoring that, i worked for several hours on one problem. i spent a long time perfecting a solution when i realized i had started with an incorrect premise. i went to go to sleep and then it dawned on me and i stayed up another 45 minutes to write down the correct starting condition. now i have to solve the problem all over again, but i think it will be correct this time. i still have three more to go after this one!
