Nad A.:
It's really not that simple to 'enjoy' the sensations. I grant that it is simple to watch them, inspect them, sample them... but to 'enjoy' them is the hard part.
Do you believe that, by default, sensate experience is neither enjoyable nor unpleasant but neutral, and enjoyment (or suffering) is something we superimpose?
If so, you might try inverting this belief in your mind. Assume for the moment that, by default, sensate experience is superb, delightful, hassle free, and perfectly satisfactory. The neutrality and lack-of-satisfactoriness which you currently take to be the default is actually a subtle layer of suffering superimposed upon what would otherwise be an intrinsically excellent, pure and fascinating "twinkling sensorium". Any attempt to watch, inspect or sample sensations from that slightly-suffering bystander perspective is tainted, because there is a subtle suffering and separation already in place, right at its root. Your belief that sensate experience is neutral and not-entirely-satisfactory validates this subtle suffering and separateness, and makes you seek something to bridge the gap. You then try to gain felicity, as if it's something you must acquire, but can't.
As an antidote, you might try to simply
be (or allow yourself to be) the sensations[1] and have confidence that, if you do, the experience of being alive is just fine.
I hope this makes sense to you.

[1] If that doesn't make sense, try this: allow yourself to not be anything other than the sensations, and have confidence that it's fine to do so.
