you can't win ALL the time, just keep pushing and eventually lady luck will budge! You have to only go after domains in four main categories...
1) natural traffic / tons of links and traffic...PPC earning names.
2) short generic useful domains for important industries - traffic irrelevant.
3) names with a known value you buy, but low enough to resell for profit.
4) current event/technology names i.e. you grabbed voip.us, etc...beat the rat race.
These are the guidelines I mostly adhere to and you pretty much cannot go wrong, the secret of course to any "sale" (if you want to call it that) is finding and contacting a BUYER...that's all that really stands between you and that ca$h..pick up the phone, send out some emails, throw out some offers...it's all a numbers game. Hope this helps!

Ps- just pattern what YOU do after other successful people, don't try to re-invent the wheel...it's still round after all these years...new ideas
are the basis of huge success but don't put all your eggs in one basket with the far fetched new business ideas, there are core values that will allow you to buy and resell domains for a profit, sometimes a quite signifigant one, don't go on a registration spree spending hundreds or even thousands of dollars...be very select in what you buy and be very attentive to detail, research some stats, learn the market and start small...and the sky is the limit from there!
