Halacha Orach Chaim 231

A person should try and avoid sleeping during the daytime hours. If necessary one can sleep what the Gemara qualifies as the length of a nap taken by a horse. There is a difference of opinion how this is translated in practice. The Biyur Halacha in Simun 4 brings three opinions. They are: three hours, half hour and three minutes.

It is prudent that one concentrate all action for the sake of heaven. This includes all pleasurable physical activities and deeds. With this attitude one can sanctify the mundane, which, essentially is our primary obligation.

When eating and drinking, one should focus one doing this to have strength for serving Hashem. When engaging in earning a livelihood, the intent should be to support ones family and to have money to give to charity. When relaxing, one should concentrate on regrouping in order to improve on the service of Hashem.

When talking with Torah leaders, one should not view himself as an honorable individual; rather the intent should be to learn from their actions. Someone that does not do this is essentially making the sanctified mundane rather than making the mundane holy. Just as it is easy to do mundane activities with the wrong intentions, it is easy to do Mitzvos and learn Torah with the wrong intentions.

One should not desire children for honor; rather the desire should be to have children so they can serve Hashem. Even when discussing mundane matters, one should try and bring sanctity to it, by intending to bring joy to others, or to strengthen the service of Hashem through it.

In Simun 155 we touched upon the discussion regarding the obligation to support oneself in comparison to spending time learning uninterrupted. The primary goal is that all our actions should be for the sake of heaven.
