My to do list.

I should be cleaning the house.
If I'm not cleaning the house I should be doing my homework.
If I'm not cleaning the house or doing my homework I should be getting my work bag ready for tomorrow.
If I'm not cleaning the house, doing my homework, or getting my work bag ready for tomorrow, I should be at the gym.
If I'm not cleaning the house, doing my homework, getting my work bag ready for tomorrow, or at the gym, I should be blogging.
And that brings us to now.
