Easy, I'd have a companion android, preferably one that can shapeshift at least slightly so that they're something new all the time. Can you tell I have commitment issues?
Second to that would be a holodeck, of course, though in there nothing I actually do would matter in the real world, hence why a companion android would be so much better. Just imagine having a loyal and intelligent partner bound to protect, comfort, accommodate, and enrich you. Of course I'd also support such an android getting free will and full sentience and would not stop them from wanting to do their own things, as long as they wouldn't completely abandon me.
