Sometimes I wonder....???

Sometimes, I wonder what really is management
Should I call it an art or science.
Then I realized it is both art and science
It is an art of making people more effective and science of how it is done
Now I wonder how to do it
Do I need to plan, organize, direct or monitor.
Then I realized they are all part of the process, I need to do all of these to be effective.
Plan in a way my goals are understood, organize in a way that my goals are achieved, direct so that people understand how to achieve them and monitor so that they are achieved right.
And finally I wonder how good a manager am I.
