You can lead a horse to water, but you can't make him drink
Figuratively: One can make an effort and provide a person with excellent conditions for success, but effort is still required on their part. In the absence of will from the person, all the help they receive will not benefit them.

אֶפְשָׁר לְהוֹבִיל אֶת הַסּוּס לַנַּחַל אַךְ אִי אֶפְשָׁר לְהַכְרִיחַ אוֹתוֹ לִשְׁתּוֹת
Definition (Hebrew)
בְּהַשְׁאָלָה: נִתָּן לְהִתְאַמֵּץ וְלָתֵת לָאָדָם תְּנָאִים מְעֻלִּים לְהַצְלָחָה אַךְ נִדְרָשׁ גַּם מִמֶּנּוּ לְהִתְאַמֵּץ. בְּהֵעָדֵר רָצוֹן מִצַּד הָאָדָם לֹא תּוֹעִיל כָּל הָעֶזְרָה לָהּ הוּא זוֹכֶה.
