All aspects of personal development are important throughout your life. There is nothing worse than meeting someone "upstart", that is to say a person who has nothing to learn from anyone. The kind of person who has seen everything, known and rejects those that are not consistent with his words and his thinking. No matter who it is, it’s very distressing to have to endure this kind of specimen of mankind.
The challenge in personal development is to accept and face the fact that we must make changes when we are dealings with others, in the way we think, act and even the way we speak. It’s difficult to make these major changes if we did not have very good reasons to do so. You don’t decide to do personal development without reason. Of course, everyone wants to improve, but few people take action or even try to know what to improve and change accordingly.
Personal development is done on several aspects. Primarily, the development is on the personality, knowledge and physical appearance. All these aspects of yourself are part of your personality. Warning! Don’t think you should work on all aspects of your personality at the same time. First, who said you had to change at all in all? Your personal development is a business that happens between you and yourself. When you decide to invest in yourself, you do for your purpose, not for others, or else, otherwise your motivation will fly as fast as the clouds in a windy day.
Here are some simple examples of personal development for you to demonstrate that to successfully grow and improve it’s not necessarily a large project. Being at the forefront of his profession by reading daily journals on the subject, learning a new language by reading or by Internet, developing skills by enrolling speaker to organizations specialized in the field and are accessible by everyone (eg "Toastmaster"); practice a sport or exercise regularly to improve his fitness and physical appearance; regularly read books on positive thinking and attend seminars on the subject, turning to part-time study in an area that really interests you.
Several options are available and don’t underestimate the impact of these initiatives as simple and small they are. If you really want to improve and develop the person you are, celebrate your successes regularly because they are all important. You put effort and sometimes you let your ego at the door to success. Success often lies in action rather than result.
