[MCU/Marvel general] What can I do with all the infinity stones other than destroying everyone and everything?

The stones by themselves individually are powerful...and sure I can create anything I want with the Reality stone, maybe go back in time a few seconds to prevent some embarrassing moments with the Time Stone. Teleport with the space stone, etc. and so on. 

But what can I do with them collectively? It seems that you can simply just...destroy people (Thanos), bring them back to life (Hulk) and destroy planets, galaxies and planets (Infinity Ultron). Is there anything like...actually beneficial I can do with them all together? Are the possibilities really "infinite"? Like would I need all the stones to make myself famous or something? Or just the reality stone?

In the Multiverse that contains Earth-616, if you get all six of them, you are effectively omnipotent and can do literally anything in that particular universe. You could turn the oceans into chocolate, make everyone into clowns, decide that gravity only works on Tuesdays, and Tuesdays only happen when you feel like it. You could make everyone immortal, or have people grow butterfly wings that let them fly unless they ever say a lie. 

That's the sort of power the full collection of all six Infinity Gems could do. 

Now, the universe got altered after the events of Secret Wars, and the Infinity Gems reformed as the Infinity Stones. They work a bit differently now, and the power of one stone can be amplified by having a specific second stone that properly resonates with it. And if you have all six, they form an infinite feedback loop where each stone powers up another and you gain that same level of infinite power.

Basically, having just one stone makes you incredibly powerful. Having more puts you closer to being a God.

How they work in the multiverse that contains Earth-199999 (commonly nicknamed the MCU) remains uncertain.
