One of the great things I love about Remember the Milk is the fact that you can use it for every single little thing. One thing I do is immediately post anything I think of doing on RTM as soon as I can, one neat way to do this is email your tasks to your account. After this I am reminded through my email (which I can easily access on my phone) so that I won't forget to do it. I do this for things from planning vacations to drinking a cup of coffee, with Remember the Milk its hard for me to forget anything I want to do.
