The practice of leadership is setting the right example, providing vision and guidance, and doing so is necessary for people within the organization to succeed. The really hard part, the art of leadership, is known as what to do, and when, why, and how to do it.
The Practice involves management. For leaders, the administration of responsibility and execution of tasks may not be glamorous, but it is essential. Without a strong attention to detail and adherence to goals and objectives, organizations may go awry. At the same time a leader needs to manage not just detail but also people. Managing people involves putting them into positions where they can succeed and supporting them in that effort.
Furthermore, whilst there are many reasons to learn more about the practice of leadership, there is one aspect often overlooked. Management is a downward process: handling the details. Leadership is an upward process: giving guidance — it is aspiration by nature. For an organization struggling in tough times, aspiration is essential; it gives a glimpse of a better tomorrow, and by extension a reason to slog through another day, week or whatever it takes. And that requires not only practice, but a degree of art to see over the horizon.
Several years ago I happened to read a book about Electronics, and I took a course related on the subject, finally and I made electronic gadgets for where I have worked. Then I decided to study Electronics at college. Unfortunately the nearest I could get was in Physics with Electronics as the main subject, hence I was qualified in Physics. The lecturers were terribly out of date, and I with a friend of college mate spent a lot of time instructing the lecturers.
