No one can overrule the fact that in order to be successful in any field, one needs to be focussed.
Lives of all successful people offer perfect testimonials to emphasis the importance of focus in your work.
But the question most people ask is how to develop that focus?
Well meditation is the answer!
Now there are several types and ways of doing meditation.

What I found to be very effective in leveraging your focus is concentration on breathing.
As per Hinduism and even Buddhism, breathing offers the vital life force. Hence when you begin to concentrate on it, you simply surrender to the vital life force and begin to engage it in your work. That's how you can leverage your efficiency.

Initially when you start with the breath concentration exercise, there will be some difficulty. Many distracting thoughts will cross your mind. But over a period of practice, you'll start getting more control over your thoughts and better focus on breath.

As a direct benefit of this practice, you'll find that your reactions to situations are better controlled. You are more at peace and your performance is invariably boosted. Consequently you start getting positive results.

But you need to maintain consistency in your practice. Even 15 mins per day is enough to start with. As you get better at it, you can increase the duration or do it at regular intervals during the day.

I am sure, like me, anyone who practices this meditation technique, will definitely get benefited and his/her life is bound to improve.
