Don't do this. Try and leave you code working at the end of the day. What I do instead is leave a bunch of @todo comments in my code when I'm done programming.

Don't do this. Try and leave you code working at the end of the day. What I do instead is leave a bunch of @todo comments in my code when I'm done programming. This does two things: It gives me some obvious starting points tomorrow and leaves those tasks fresh in my mind as I go through out the rest of my day. I often come up with really great solutions just from writing a very simple @todo sentence.
