רֵאשִׁית חָכְמָה יִרְאַת ה' שֵׂכֶל טוֹב לְכָל עֹשֵׂיהֶם תְּהִלָּתוֹ עֹמֶדֶת לָעַד
The fear of Hashem is the beginning of wisdom; a good understanding to all who practice it; His praise endures forever.
Upon arising, one recites Modeh Ani, followed by this verse, Reishis Chachma. The Metzudas David explains that when one starts to study wisdom, he should do so based upon a foundation of proper awe of G-d. Good sense will enlighten one who does so and he will end up being praised for his enduring wisdom. This is not true of one whose studies lack such a foundation.
