'Realize' is a strong claim, experiences may indeed be meaningless or they may not be. How could anyone ever prove one way or another? But if one could be convinced they were indeed meaningful, it might provide an avenue for happiness.
May I ask is it possible you desire something to desire?
Yes but it's also a practical psychological question. A person can come to a mental state where nothing in life interests them yet they wish there was something they enjoyed.
So, although possibly mundane, there is a point of view where the question "does anything in life have meaning" is less interesting than the question "is everything ok".
