Do you feel that you lack enough concentration, and would like to strengthen it?
Lack of concentration seems to be very common, especially nowadays, with so many distractions, so much information, gadgets, advertising, and products that attract your attention in so many ways.
This happens everywhere, at work, at school and at home. Walking, eating, exercising, studying, and almost activity, are done with a divided attention, and therefore, not so efficiently, and at the risk of making mistakes and errors.
What is concentration? It is the ability to control the attention, choose on what to focus it, and reject irrelevant thoughts and distractions. It enables you to become the master of your mind, and not the opposite.
