How do you choose your Pogo personal challenge?

i don't usually do the personal challenges anymore. I have my badges all caught up. so now the only time i do a personal challenge is if we need them in order to get the special badge they have sometimes. But when i do need to pick a challenge i usually pick the games i like first. when i was trying to get all my badges caught up I picked ones depending on what else i had going on. if the other two badges were going to take some time then i would pick an quick easy one. i saved the harder ones and ones i didn't like for badge days that i knew the other two would go fast.

I mix it up, sort of. I'm trying to work through the 2007 one right now. At first I just chose games I liked, now I'm going through, mostly, in order from the begining. But if the weekly challenges are tough, then I usually have to skip a few of the tougher ones and find an easier one to finish. Unfortantely all I have left of 2007s is card games and solitaire games. I'm finding them very difficult to finish. I'm doing one this week that is my second time trying to win. I've yet to do it in the allotted week!
