It's almost a classic mistake to buy names that we really, really like - with no other favorable criteria. You have to accept that the reason these names were there for the taking was because absolutely nobody in the world was willing to pay $10 for them. That could change tomorrow, but they have literally been unwanted for years to date.
I still register domains for no reason other than I like them. Some even sell, shockingly. But it's not a good business model. Eventually, I let most of them drop after the love has worn off. Use only the money you can afford to lose for these kinds of purchases.
