If you’re one of those people who, like me, have a daily to-do list, then try teuxdeux
It’s a really neat site, where you can keep your daily to-do lists. You put a red line through things you’ve done. Things you haven’t done are automatically shunted on to the next day at midnight.
And there’s even a some day section for items that are less urgent.
Put it on your to-do list now.
