Part of the problem is that it's time for me to add all the things I need to do for next rem, because I know I won't be getting much done in Mexico. So I have syllabi to write and readings to review. But as you can see, the fact that I keep my grades in a databse on the computer makes it all too easy for me to comment rather than work.

As for the writing, don't be terrified. You'll be fine.
