me: had a great track workout this morning, finally got a decent time progression (slower ---> faster) and finished stronger than I'd expected. And was still able to jog home.
Just finished all Mathematica excercises. Damnit, it took about eight frickin hours. And now that I know how to do it, I could do it in 30-45 minutes... Anyway, still very happy about it. Not so much that I have to read 70 pages now.
