The ugly part of writing is starting, the fear that your writing won't express what you want, or won't match up to the quality you produced yesterday. This is not real, because I have enough energy to play games. No. Don't pretend you're actually tired. Your brain's just looking for excuses not to think. Too tired to lie in bed with a laptop on your lap? I think not.
I can't write when there is anyone else in the house, unless I'm in a library. Silly? Perhaps. Forcing myself produces crap however. If you have a more productive location go to it! If you haven't found it, by all means search. If you're already productive, you could find yourself more so in the right sort of place.
I have to do the dishes first. I haven't written that email. Oh, god! I can't put that off, but I can put off my writing. This is the worst one for me. I have more time than I did when I was younger and at school. How come I don't write as much? I didn't have responsibilities to take care of or stress about. Apart from homework. Instead of setting aside writing time, why not set aside 'responsibility time', where you have an hour or two to take care of everything that's hanging over your head. Then you have the whole night to write. If it will take more than two hours, forget it. It can wait until tomorrow. Important stuff only. Everything else on the 'to do' list.
