Having goals without the focus and drive to pursue them is useless. Nearly every individual has dreams and aspirations, but what's important is to work towards achieving those goals. Success does not come by chance, maybe on very few occasions. Depending on luck when it comes to achieving the things that we desire is not very practical.
When we set goals, we have to stay the course, keep the focus and have the right attitude in order to realize them. Many people talk about what they want in life, the kind of things that they aspire to achieve, yet very few of them actually put enough effort to realize them. Self-discipline and success go hand in hand because that is what will ultimately help you keep on the right path.
It's easy to get distracted by bad choices, so much so that you end up chasing after the things that don't really matter. As you grow older, nobody will police you to do what is right or make the best choices. It's all up to you to make the right decisions. This is where self-discipline comes in since it will help you make the right choices even when nobody's looking over your shoulder.
It's very simple; take even an example of students who are preparing to sit for an examination and are left to study on their own. Some will use that time to go over the teachers' notes and really grasp the subject in question. Others will engage in mischief and waste a lot of time and resources doing things that don't really count simply because nobody is supervising them.
At the end of the day, the focused and disciplined students will get good grades, while those who have to be watched over in order to do what is necessary will most probably fail. The most important lesson to learn from this is that your success is your own, and as such you should be motivated and driven to work towards it even without being reminded or pushed to do so. The same applies in life and the pursuit of success.
Self-discipline will be the major difference between those who realize their goals and those who fall by the wayside. If you know your destination and understand the scope of your journey, staying focused on the things that matter will see you realizing your dreams. The elements of success are very straight forward, and self-discipline is right there at the top of the list.
