1. Turn on music. Ideally as loudly as possible. Nick Cave's "Thirsty Dog" is doing my wonders right now because I'm in sort of an angry mood and it's just a great angry song, even though he spends the whole time apologising. "(I'm sorry about all your friends/I hope they'll speak to me again/I said before I'll pay for all the damages/I'm sorry it's just rotten luck/I'm sorry I've forgotten how to fuck/It's just that I think my heart/ and soul are kind of famished" may be among my all time favourite Cave lyrics).
2. Find wine. Look you don't even have to drink it but a glass of wine in your hand cannot NOT cheer you up. That's not me, that's science speaking.
3. Dress up. UP I say. The shitter you feel the better you should look. Which is why I hope and plan to look pretty fucking good tonight.
4. Get off the couch. Sorry, that should probably have been the first step actually.
