Serving out of love?

Hilchot Teshuvah 10:1 “One should not say: I will fulfill the commandments of the Torah and engage in its wisdom in order to receive all the blessings written therein… or in order to merit the World to Come… It is not fitting to serve God in this way.””One who serves in this manner serves out of fear. This is not the level of the prophets nor the level of the wise. Rather, only the common people, women, and children serve God in this way. They are educated to serve out of fear until their knowledge increases and they serve out of love.”

Question: What percentage of the population reach this level of serving out of love?
