Is there an ultimate strategy to big brother?

I've always wondered if there was a perfect strategy to win big brother.

I'm not exactly certain, theres never a year where theres the same scenario.

What would be your strategy going in?

Would you be quiet, would you want a day one alliance?

Me personally, I'd keep my head low, but not too low that its suspicious.

I would make a solid game decision to please the house, then form my groups through to the end.

What would you do?
