I was pushed to be a good student in high school. Absolutely useless. I wish I only cared about math and English. I actually tried this sort of focus on a few subjects, but you know how it goes -- everyone and their momma is convinced you gotta be "well-rounded" i.e. study a bit of literature, history, geography, art etc and come out knowing precisely jack shit.
I had to take care of our dog, including chasing him down when he got out of the yard. Wasted a lot of time riding my bike around looking for him. One day he got run over by a car.
