most domains, including one word domains, will not get any inquiries at all. Domainers usually don't talk about this but you could own a portfolio of 10,000 .com names including exact match domains with major search volume, names that might've sold once for 5 figures, names that were at auction that had 40 unique bidders, and you will sit without a inquiry for years or decades. If you do get some offers, most will be 20 dollar offers for your best names and the offer will come from someone with an IPv6 address that links back to a 5 dollar phone connected to the web using 3G.
To survive as a domainer you must delete a lot of your names and hold on to the good ones long term and price them very high. Expect to hold on to a name about 15-20 years and if you have enough good ones, one sale will cover the others plus you will be able to treat yourself to a McDonalds happy meal and have some change to buy a 2 dollar lotto scratch off and hopefully win 7 bucks so you can renew your nampros membership, it's worth it in my opinion.
When I do sell a name and I get the notice from afternic or dan, I try guessing what name sold. I never got it right in over 10 years. Sales also come when you least expect it and usually they come in pairs, and then quiet. The worst feeling in this business for me is when I agree to someone's offer and they vanish. I understand brokers that ask you pay them a small fee to help secure a name.
Don't feel bad about yourself, you are just like 99% of all domainers. Read as much as you can, follow some auctions, read about trends, look at names that sold and the hold times when they are available.
