Heaven on earth

Would heaven really be a place where it's blissful for all eternity? Or is like earth, where one might get tired of it after a while, and want to go somewhere else, see other things.  Maybe it's all just perspective. Perhaps heaven isn't a place where souls go, but rather a state of mind. When I'm happy, when everything is going well, this earth is my heaven. When it's not so great, it's just the cruel cruel world.  And perhaps when I'm suffering, when things are at their worst perhaps that's one of the levels of hell.  Maybe heaven and hell aren't places, but metrics. Maybe they're units that we can measure our levels of happiness by.  Since there are levels of hell, why not levels of heaven? If so then the challenge isn't so much getting to heaven, but rather staying there.  How would people live differently if they thought like this? That instead of eternal bliss in the afterlife, there is only bliss in those few short years that you're alive to experience it.  That you don't get to be happy because some omnipotent being decided that you 'deserved it.' You get to be happy because you decided that you like where you are, who you are, what you are. You're in a good place, and so you decide that that place is heaven.
