@bekind Everyone on this forum had to start from scratch and along the way to getting where they are now, many of them will have bought some names that weren't great, or they bought names for a niche that didn't work out/didn't work out the way they thought, some gambled on junk extensions (shockingly, lots of people are
still doing that for some strange reason (SMH)).
So many people have scars from bad decisions/bad luck, but those who could kept on and got better and better at this. You can do that too.
I don't know how long you have been buying domains, but if it has been less than 10 years, you must remember that there is a finite number of useable words as domains and the available pool of such domains is getting close to being very small. This is because the golden age of domain names was over more than 20-25 years ago.
If you find a name that is available, you should stop right there and ask yourself why no-one owns it already.
Ask yourself;
1. Is is because I am so great that only I could have come up with this name?
2. Is the name available because it is not desired by anyone?
Which answer do you think is more likely to be correct, in 95-99% of cases?
Because domain name investors generally operate alone in front of a screen, it's very easy for some of them to think they have found a name that is good/great and convince themselves that they will sell it easily or soon.
The risk of self-reinforcing delusions is very real risk with domain name investors.
As Brad above said, even great names takes years of waiting for a buyer to come along.
Unfortunately for the names you have, they are very poor and not worth even the renewal fee. I would let them go when they come up for renewal.
I would suggest you learn from this experience but don't let it be what defeats you. Spend some time (at least 6 months I woukd suggest)
to learn what a good domain name actually is. This site has resources on this and there are other resources you can find on the web, YT, etc.
You may not be able to find great names that are unregistered, but you might be able to find some good ones for $xxx which you can then resell for much more.
