It is very important to study Halacha. If you can, study all four sections of the Shulchan Aruch in order from beginning to end. Otherwise, study one of the concise guides that explain the laws of daily life.
The study of Halacha is a great spiritual remedy. When a person sins, good and evil become mixed up. Each individual Halacha is a legal decision that makes a clear separation between what is permitted and what is forbidden, what is clean and what is unclean. When you study Halacha, good is once again separated from evil, thereby rectifying the sin.
Every Jew should study Halacha every day.
If you are under pressure and have no time, study at least one paragraph of Halacha on any subject, even if it is outside your regular study schedule. Learn at least one law every day of your life.
(Rebbe Nachman of Breslov)
