A person who has good self-control has the ability to control oneself, in particular one's emotions and desires or the expression of them in one's behavior, especially in difficult situations. Self-control is the ability to regulate and alter responses in order to avoid undesirable behaviors, increase desirable ones, and achieve long-term goals.
10 Ways to Improve your Self-Control...
Have A Can-Do Attitude - Viewing ourselves as free and responsible for our actions is the foundation for self-discipline.
Set Goals - One has to have a goal. Goals basically guide our choices. The more specific the goal, the better able people are to reach it.
Self–Monitor - Self-monitoring is a form of feedback. Monitoring the progress towards a goal helps one to concentrate on goal-relevant activities.
Motivate Yourself - The more you want the goal, the more likely you are willing to make the efforts and sacrifices required to achieve it. The strength of people’s commitment.
Have Confidence - An important component of motivation is the person’s self-perceived ability to achieve it. People won’t build up much motivation for change if they believe it is impossible for them.
Have Willpower - Willpower represents strength or psychological energy that one uses to resist other temptations in order to work toward one’s goal.
Avoid Temptation - Avoiding temptation requires anticipating situations where unwanted desires might emerge and taking proactive steps to ensure that one doesn’t succumb to the problematic desire.
Understand The "Why" and "How" Mindsets - “Why” questions encourage long-term thinking, or desirability of pursuing an action. In contrast, “How” questions bring the mind down to the present and consider the goal’s attainability or feasibility.
Make Self-Control a Pattern of Behavior - While the physical independence of today and tomorrow is real enough, the fact remains that actions today affect actions tomorrow. Self-control comes from choosing “patterns” of behavior over time rather than individual “acts.”
Have Automatic Goals - Goal pursuits can be enhanced by a simple planning strategy: making if-then plans that connect a certain triggering situation with a concrete behavior.
