Spreading Yourself Thin: How Many is Too Many?

Hi All,

Just hoping to start a little discussion on here with regards to something that has been on my mind recently.
The summer holidays, for me, are one of those times where I always intend to organise a few days to get some of my many games to the table.
As we're rapidly approaching the end of said holidays and I've almost entirely failed to do that, coupled with trying to arrange days with my other (primarily RPG based these days) group, while also trying to figure out days/evenings to play some of my many miniatures games and also pondering trying to arrange some days to get specific board games to the table, and all the other 'real adult life' things, I'm starting to wonder how I'm ever going to fit all of it in. 
Not taking into account my board games or RPGs, the list of games in currently invested in stands at:

Warhammer 30k
Warhammer 40k.
Necromunda
Kings of War
Guild Ball
Dark Age
Batman Miniatures Game
DC/Marvel Universe Miniatures Game
Star Wars: Destiny
SW: X-Wing
SW: Armada

It gets even more frightening when you start breaking it down further, as its not even as if its one army/crew/gang/team/deck etc. per game system. Its multiples for each one.

At what point am i going to be able to give all of these games a fair crack of the whip?

Time and again I'm asking myself: Is it time to start trimming some fat? Just rip off the plaster and reduce the list down to a more manageable number of systems? Can you even bring yourself to do it?
None of these are bad games. How can you decide which go and which stay?

Anyone else finding themselves in the same boat?
