Self-discipline is the act of disciplining or power to discipline one's own feelings, desires, etc, especially with the intention of improving oneself. Without self discipline a person isn't able to truly be in control of their lives. Paying bills, studying for class, and even personal hygiene all require self discipline.
Troubled teens and young adults generally implement self-discipline, but discipline that is directed towards the wrong priorities. Friends, video games, partying and acquiring harmful and illegal substances are all things troubled teens and young adults tend to focus. Additionally, troubled young people lack discipline in all of the important areas such as school, work etc.
If troubled young men and women fail to achieve good self-discipline, the consequences may be dire. Young men and women will grow into dysfunctional adults who have a higher risk of falling into negative behaviors and habits such as drug and alcohol addiction.
