Lack of attention span when sticking to a game

[Haly]

I always find I end up owning loads of games (Although guess that will change once I'm jobless ) yet only completing a small percentage of them. I tend to play through to a certain stage then get stuck or bored, and go play another game and so on.
I don't think it's down to how many games I have because I've always been like it as long as I can remember. Although I do know I have a terrible attention span and get bored easily (Lately I've been watching films while playing on the DS and I still seem to be able to concentrate fine on both, doing just one gets boring :undecided: ).
Just wondered if anyone else is like it

I'm hoping once I have no income so I have very little chance of buying myself games, that it provokes me into completing my back catalogue.
