I have been on the quest for winning at life for a long time. But nothing could prepare me for a run-in with a lesswrongian.
My life has been turned upside-down, it turns out that every aspect of my life can be considerably improved or upgraded, but there is so much to do that I'm completely overwhelmed by all there is to do.
The improvement to-do list is a mile long and I've currently reached the point where I'd rather wallow in self-pity than actually get up and do something...

Help,Please.
