“Thoughts lead on to purposes; purposes go forth in action; actions form habits; habits decide character; and character fixes our destiny.” (Tryon Edwards)
Almost everything you are or will be will be determined by your thoughts, feelings and behaviors. Fully 95% of everything you think, feel and do will be determined by your habits. The key to becoming a great person, and living a great life, is for you to develop the habits of success that lead inevitably to your achieving everything that is possible for you.
Fortunately, all habits are learned, and are therefore learnable. If you have bad habits, or if you have not yet developed the habits that you need to become everything that you are capable of becoming, you can develop these habits by a systematic process of practice and repetition, just as you learn any other subject.
Good habits are hard to learn, but easy to live with. Bad habits, on the other hand, are easy to learn but hard to live with. In either case, once you have developed a habit, it becomes automatic and easy. Like breathing in and breathing out, you find it easier and easier to engage in thoughts, feelings and behaviors that are consistent with the person you want to be, and the goals you want to achieve.
