Thoughts?
I think you should ask yourself if you are registering these domains to develop or to resell.
If you are a developer then I think you have registered too many domains to develop in a lifetime. If you are looking to resale then I think you need to focus on higher quality domains that must be purchased as they won't be available. But even this will be EXTREMELY difficult. What you are trying to do now is impossible.
If you are independently wealthy and/or just doing this as a hobby and/or not in this for money, then you probably don't care if you make money. I like to make money. If you like to make money, grace delete all of these and rethink your entire domaining strategy.
Start to think about domaining like any other business. If you are able to make 50% return on your money, you are doing remarkably well. If you want to make a $5.00 profit, it will take a minimum of a $10 investment. If you want to make a $100.00 it will take a $500 investment. And this is all based on you executing to perfection.
The main problem with domaining is that there is a ridiculous amount of supply in the pipeline. Imagine trying to sell suntan lotion to eskimos during that month long-blackout they have up there or try selling sunblock at a tanning parlour.
That's what you're up against in this business. You need to find product and it's not in the available pool, and it's not in drops, and it's not in the $5 BIN at TDNAM. The best advice you could get would be to slow down on 'domaining', purchase 1 or 1 killer domains, develop or flip, then repeat.
~end of ramble. Hopefully there's a line or two in there that you can use.
