question New domainer in the community

Hey all,
This is my first question in the forum, first of all I would like to thank you all for such a great content - This is a priceless forum!

I took courage after two weeks of reading posts here - and bought 3 domains for start.
I read here that everyone suggest to sell quickly domains to gain more experience and money for start,
And I posted my domains in Namecheap and Sedo a week ago, still no trafic to my domains...

What should I do further?

Thanks!
