Am I destroying my PR7 domain?

Why did I get this picture in my head?
If you're not trolling and got a pr7 site you should hook up with someone on the site, sell it, let the person build it and give him a % of the cake. o do a giveaway with D0 follow links!

With your ideas and that level of SEO knowledge you'll just ruin that good domain and Google will deindex it forever.

Just be smart and listen wise advices from experienced people above. Keep your domain, learn some SEO. There is no need to hurrying.
