Life is available only in the present moment.
This is the only moment that exists, and this means that you have to focus all your actions and your awareness of the present moment. Living and making things happen happens in the now, in the present moment.
You eat in the present, work in the present and interact with people in the present moment. Becoming conscious of the present moment, and focusing it, instead of focusing on the past or future will enable to control the present and the future and enjoy them more.
When you live in the present moment, which means being aware of the present, of your actions, and of what is happening around you, enables you to be more aware of other people and of what they think. This makes it easier to get along with them.
Living in the present improves your focus and your awareness of opportunities, which otherwise you would have missed.
Focusing on the present also helps you calm your mind, because you do not allow worries, fears and stray thoughts to occupy your mind. This, of course, helps you use your time more efficiently.
