Se’if 1א׳

אַחַר שֶׁיֵּצֵא מִבֵּית הַכְּנֶסֶת, יֵלֵךְ לְבֵית הַמִּדְרָשׁ; וְיִקְבַּע עֵת לִלְמֹד, וְצָרִיךְ שֶׁאוֹתוֹ עֵת יִהְיֶה קָבוּעַ שֶׁלֹּא יַעֲבִירֶנּוּ אַף אִם הוּא סָבוּר לְהַרְוִיחַ הַרְבֵּה. הַגָּה: וְאַף מִי שֶׁאֵינוֹ יוֹדֵעַ לִלְמֹד יֵלֵךְ לְבֵית הַמִּדְרָשׁ וּשְׂכַר הֲלִיכָה בְּיָדוֹ, אוֹ יִקְבַּע לוֹ מָקוֹם וְיִלְמֹד מְעַט בְּמַה שֶּׁיּוֹדֵעַ וְיַחֲשֹׁב בְּעִנְיָנָיו וְיִכָּנֵס בְּלִבּוֹ יִרְאַת שָׁמַיִם (הר"י פ"ק דִּבְרָכוֹת).

To go from the Synagogue to the House of Study. Containing 2 Se'ifim After he leaves the synagogue, he should go to the house of study and establish a time to study [Torah]. And it is necessary that this time be fixed, such that he does not skip it even if he believes he can earn a lot [of money]. Rem"a: And even one who does not know how to study should walk to the house of study, and he will have the reward for walking [there]; or he should establish a place and study a little of what he knows and think about his ways and [by doing so] bring fear of the Heaven into his heart (R"i in the first chapter of Berachot).

Se’if 2ב׳

קֹדֶם שֶׁיֵּלֵךְ לְבֵית הַמִּדְרָשׁ יוּכַל לֶאֱכֹל פַּת שַׁחֲרִית אִם הוּא רָגִיל בּוֹ, וְטוֹב שֶׁיַּרְגִּיל בּוֹ.

Before he goes to the house of study, he may eat the bread of the morning, if he is accustomed to doing so. And it is good for him to accustom himself to it.
