Leadership Versus Management

There are dearth of materials on leadership and management. You are also list the role of managers and leaders on daily basis. But it is very difficult to distinguish between two terms. Although many experts and educationists have given some characteristics to differentiate between leadership and management.
In my opinion it is very difficult to distinguish between two terms. You cannot say that it is the role leadership and it is not role  of leadership. Similarly, you cannot say that it is the role of management and it is not role of management.
In my opinion and experiences, in same time you perform both roles and in same time you perform different roles. It is very difficult to differentiate both roles. Both are interchangeable. However, we need to specify some roles and characteristics one for another. Some of the difference are as under:

The leaders have active attitude towards goals while manger have passive attitude towards goals.
The leaders do right things while manager do things right.
