Seize the day.
Or more precisely, if you see a 60Gb PlayStation 3 in a second hand shop window for £245 don’t agonise for forty-eight hours about whether to buy the damn thing or not. Just buy it. That way you’ll not be disappointed when you go back and it’s been sold. Probably to someone who’s going to flip it on e-bay for double the money.
Yes, I’m stupid. Feel free to point and laugh.
