What percentage of our duas concern matters of this life vs matters of the hereafter? Don’t misunderstand. All duas no matter what the subject matter, small or large, worldly or otherwise, are beautiful and acts of worship when they are sincere and to Allah alone. Not trying to discourage anyone from turning to Allah even for the most insignificant or quotidian matters. Even the boy who prays that there is pizza and not liver for dinner tonight, even that can be a weighty act in the eyes of his Lord and He will respond and answer that prayer undoubtedly.
