What makes me happy in LOTRO these days are the memories of all the fun I had over the years.
I really wish I could say the same about the newer Gondorian areas of the game, but for me they aren't the same, too many graphical/performance issues to keep me absorbed in the beautiful setting for hours the way I was in earlier areas. Now my level 100-ish gameplay is interrupted so often by various issues that when I do play, I stick to the lower-level areas on my alts. I still haven't made kindred with Minas Tirith and that's highly unusual for me.
But when I go to my house or visit my kinhouses, seeing all the items and remembering the fun I had acquiring them, that can still bring a smile to my face.
“All that is gold does not glitter,
Not all those who wander are lost;
The old that is strong does not wither,
Deep roots are not reached by the frost."
