Time warp is an actuality which we fail to notice and so is space warp, but both these things are difficult to notice until you start seeing spaces more than you see things.
Once you start seeing spaces, you'd realize it's not happiness that gratifies, but a thin, light being you experience, some call it peace, some call it contentment, how one can differentiate between the two is another matter we can choose to discuss at length.
And it is not efforts that prevent us from achieving that peripheral vision, nor is it failure that does. It's something else and you see it when you observe spaces. Ask any sportsperson when he performs at his best and he'd tell you he can't explain, it's a zone he gets into where he doesn't need to try too hard to concentrate,but at the same time all would concur that as soon as that attention is compromised on, the zone dispels. So are we not supposed to be able to see that it's not the objects in front of us that we are to concentrate on, but where their boundaries blur. If you can see where something ends, you can also see where something begins.
So when nature offers happiness through different media, it is offering you objects, but what you need to see are the spaces. If one has ever experienced the peace that results when stares into the blank, one might find it a likelier point to agree to. And then you might also find it easier to understand why theory of uncertainty makes sense.
