That was great insight. I think the main question was about keeping the same interests when we leave here, which we see as instrinsic to our personalities. For the OP, will he remain curious about the same things and discovering more about them.
Will there be curiosity in heaven? Will we wonder about things. We will probably be in wonder, but not wonder. We will have full knowledge of everything we can know and that will primarily be abut God Himself, I think. We will not be absorbed with wondering about the creation, but rather absorbed by looking at the beauty of the Creator and never tiring of doing that, because it is always new.
Well . . . I’d hesitate to say that, frankly

. Jesus mentioned that the angels in heaven long to look into the things of the end, if I recall correctly. Which definitely would be curiosity. The martyrs in Revelation also are portrayed as pleading with God, “how long until our blood is avenged?” And he urged patience, that it would come when the fullness of their number was complete.
Entering Heaven does not grant omniscience. And anything of God that remains unknown to us, is stands to reason we’ll want to know more about

. I suspect it’ll instead be a time of infinite discovery, because God Himself is infinite.
I could be wrong, of course

.
The things we study now we plod and grope over with dulled intelligence to make small gains. In heaven awareness and knowledge is poured into the soul. This is only speculation on my part. What is not speculation is that things will be very different when we leave sin nature behind.
I suspect we will indeed have knowledge poured out into us and far more available to us. There will certainly be fewer barriers between us and knowledge because of the completeness of our unity with Christ, “The Wisdom of God.”
On a different note, I completely agree with Gottle of Geer about sin’s impact marring the personality. In Heaven our personalities will be completed, fully human. Sin mangles the personality. Its absence will make us fully human, fully ourselves, or who God meant us to be.
As for our current interests- if we lose them, it will only be because we find that we have more interesting things to focus on

. Which we very probably will

.
But I suspect that our interests, like our personalities, will be in some way “fulfilled,” brought to the glorious completion God has in mind for each part of who we are. That’s just my suspicion.
