Rectifications for the Days of Shovavim

In the book "Taharat HaAyin," it's brought in the name of the Rokeach that the initials of luck are "In wasting seed," meaning that a person's luck and abundance in life are directly dependent on guarding the covenant.
Hasidism explains that all elevations and declines in all matters depend solely on this, hence this trait is called "foundation," as it's the foundation of a person (Netivot Shalom I,7.

"The breach of the covenant" is the most serious of all sins (Shulchan Aruch, Even HaEzer 23,1), as if spilling blood, practicing idolatry, and is punishable by death (Tractate Niddah 13b), potentially losing one's share in the World to Come (Reshit Chochmah Chapter 17, p. 500), causing issues in the nervous system and psyche (Adon HaMiddot p. 19), and also delaying redemption, which depends among other things on correcting this breach (Binyan Yosef p. 15).
The main days for rectifying the breach are during the Days of Shovavim, the counting of the Omer, the three weeks, the festival of Sukkot, the festival of Chanukah, and the Ten Days of Repentance.
So how do you stop and break free?
You stop by deciding to stop (Taharat HaBrit p. 14). In Parashat Bereshit 4, it is said to Cain, "And towards you is its desire, and you will rule over it," which Rashi interprets there - if you wish, you will overcome it. It mainly depends on guarding the eyes, the eye sees and the heart covets, and from this falls into sin.
