Goofus
In actuality you are asking to understand everything Hashem understands.
This is a wonderful aspiration
But of course not possible. Certainly not in this world. In the next world it’s not possible either. But there, there is a constant and continuous elevation of the daas higher and higher closer and closer to Hashems Daas (which can never be reached). There will be more than Simcha. There will be constant laughter because of the new exhilaration and indescribable pleasure of every moment as ones understanding of Hashem grows. This is what Rav Shimshon Dovid Pincus ztl explains.
