     [1] Why can't I get it done?

     [2] This is one question millions of people over the globe ask themselves every now and then. It is not

as if you are not working hard, but you simply may not know that there is a difference between work and

productivity. Your plan is what gives you a clear picture of what you are aiming at, but the method of

achieving may vary from time to time. That you did not meet up with a deadline does not mean you were

not working on it. The problem is whether you will be able to manage time.

     [3] Before you start on the next activity, task or project, first ask yourself why you want to do what

you are about to do now. You will by this be able to know if the task should be done, and if the timing is

right.

     [4] Doing the right thing at the wrong time makes it absolutely wrong. So it is not just enough to do

what is right, also consider           . Your time has value, when you spend it on what is right at that instance. On the other hand, the value of your task is when it is done at the right time.

     [5] You will feel sorry about the time spent on what was not profitable to you. Time can not be wasted, because it can not be preserved and replaced. You are always doing something with your time. What

matters is the value of what you are doing at the moment with your time.

     [6] The desire to make a difference begins with the ability to take the right decision on what to do. It

will become simple if you learn to manage time effectively.
