Google updates and panda what is up?

Hi,

As a noob, I will discuss with you about my strategy after all the google updates and panda slapes or whatsever.What I should do or what should I avoid?
Google slaps mini sites, google slaps bigger sites, but what would google
look today?

What does google will be at all?
What must I notice to build an longtime stable online business?
Here and there, today and tomorrow,google says this,another day this...
Google does not say; I need bigger sites who has 100 pages, or I need only sites who has max.500 words unique content on every pages.
Or; I dont like amazon,affiliate sites, or whatsever, all this you don't find in google TOS.

What is google looking today?

Is ist dangerous to build small concentrate mini niche sites who have only 1,3 or 5 pages with long product review, long content about 800-1200 words?

Or is it dangerous to make adsense micro sites, pages who have only max. 200-300 words on content?

Or is it dangerous to build up many thin affiliate sites -amazon or affiliate products, like the mini site example above?

Does a site must have many pages,like 30,50 100s?????
Or does a site must have many long written unique content, lets say 800 words on every page?

Or whatsever?

Which google rules are should I follow- to must have daily fear about that google will deindex or slap me overnight?

Please discuss with me I'm happy to hear about or get some good tips from the grurus here.

best wishes
