Friends, can I have some advice for the Sunday Million?

[1C5]

I am getting staked, I never played a tourny this large before, I know I can ask this in the MTT forums but that would be useless as no one knows me there.

I of course played many 1000s of SnGs but have moved to 6 max NL cash games recently.

Just looking for some general advice on the correct way to play during what stages of such a large tournament.

Thanks!
