Winning individual challenges is stupid this early in the game. No matter how much the Chenbot promotes it, it will always be more for show than for dough. Not until the very end when your neck is on the line should you try to win. Of course they'll say that winning is huge because they wouldn't want everyone to throw challenges which would make for boring TV.

Rare exceptions?
Will in BB2, Tina, Vee, Sandra (twice), Amber, Chris, Danni, Aras, Yul, Earl, Todd and Natalie hadn't won an individual challenge before F6 but went on to win. Will, Tina, Vee, Sandra, Chris, Danni, Earl and Natalie didn't even need to be on a winning team. Strategy is always better than winning challenges.

Say what you want about casting but you'd be their perfect candidate! Giving 110% effort in challenges would be the surest way to make enemies. I'd be in the shelter laughing and planning your elimination. Oh! The drama of the athlete robbed of his "deserved" victory!!
