It is not impossible
Many people who were raised in Western Society steeped in the Klipot, believe that it is impossible to be Shomer Habris. This is not true. There are thousands upon thousands of people in Eretz Yisroel and throughout the world that are Shomer Habris, amongst them many that are single and not married.
For those that claim that if a person never fell into these Klipot it is possible, but one who has unfortunately stumbled has no way of picking himself up, this is also not true. There are many Balei Teshuva, who in the first part of their life committed many severe sins. Later they managed to rectify their life and become Shomer Habris.
The first thing a person needs is the will to stop. It is going to be a tough battle and a person must be truly committed to stop. A person should recognize that although his animalistic soul is still very attached to these Klipot, at times even controlling him. He himself knows that it is a terrible sin and he is petrified of committing it. He must have the will to want to be Shomer Habris. If he was given an easy way to do it, he would go there immediately. Now that there is no easy way to remain pure, he commits himself to fight with all his power.
There is only one way to reach this will, that is to read as much as he can about the severity of these sins and the damage that it causes. Even though this topic is ignored by Western Society, it does not excuse one from researching this topic.
Although there is only a small amount of information on this web site (www.briskodesh.org), one should begin with this. There is also a list of Sefarim that deal with this topic. A person should try his hardest to study as many of them as he can.
