I've never had to put a great deal of effort into anything. It hasn't come up yet, but I know this will eventually bite me on the ass.
I've got to really be able to see the benefits to motivate me to do... anything.
I am heavily effected by losing, which is worsened by the fact that I gain very little joy from winning, or being anything but the best, and don't like to let challenges pass by. I absolutely hate situations with no clear win conditions.
I am bad at social situations and averse to strangers to the point it appears almost sociopathic.
I accentuate my faults and consider my good points to be the minimum that should be expected, which makes me hold myself and other people to very high standards.
Err...
Fuck, I've not even started.
Just for a bit of meta self-deprecating fun; I'm a whiny ***** who likes to moan about how much I suck in order to gain sympathy, and make heavy use of wit and humour as an (often pre-emptive) defence against criticism and scorn.
