He said, "NO personal comments about my way of doing things please."
The first thing you did was point to his personal way of doing things. You did this against his request. That's not cool.
That's what I did too, albeit in an indirect manner. You can't have a real debate without criticism.
The conversation was steered in a way that discards arguments against handregging.
Yes, patience is required (not to be confused with
stubborness). Even good names can take a long time to sell. I understand that the OP has not been at it for a long time. So he must be thinking it's normal he's not made sales yet, and his time will come. Unfortunately the odds are stacked against registrants, especially when the domains are not compelling. 99% of domain names parked for sale are waiting for a buyer who will never come.
If a name is still available in 2018, it usually means nobody would even buy it for $10 and you should think twice if your aim is to resell it for a profit.
Hint: you can use sites like hosterstats.com or archive.org to find out if the name was registered in the past.
There are members who post names for appraisal, names that were
never registered before (in two decades of Internet history and in spite of billions of eyeballs), or names that used to be registered and dropped ten years ago. What are the odds of a big sale to an end user with names like those.
It takes research, discernment, experience and gut feeling.
I think the OP will struggle to sell just one name in the portfolio, even if he does - that won't be enough to recoup the investment.
At first glance, I would advise not to renew any. Don't waste more money on renewals. Instead, use your disposable income toward the acquisition of fewer but better domains. Good luck. If domaining was easy everybody would be doing it.
