Thank you guys for the nice comments!
What I did:
I choose new micro niche that run about 2 month, keyword research not available because everything is new. so I just look for my competitors and there just 2-3 big ones, wikipedia and new ones.
-bought hosting with zettahost, build wordpress site with twenty eleven theme, add ads.
-start building web 2.0, try to do some social shares, forum posts
thats it. now i rank first page first place in 2 keywords, and first page 5~ place for one.
I keep building web 2.0 not for my home page.
One thing about zettahost. I experience some DDoS attack on my site and they just suspend my domain and not allow me to open the site again on their server.
I moved to A2, good costumer service, very fast hosting, I experience more DDoS attacks with them and they help me to protect my domain with cloudflare.
Thats it. right now I bought 3 more domains that tagets new micro niches that will come soon (according to TV, just look at TV promotions and target something that come soon).
Looking forward to double the daily income
Good luck guys
