There are many kinds of meditation and many reasons why some form of meditation should be part of your life. The brain science confirms what practitioners of meditation from around the world and for millennia have long known. Meditation has a wildly salutary effect upon the brain, the mind, and the whole body-mind. On the whole, it will make you a better and happier person. It will improve your life and that contagion cannot help but spread.
Find a teacher, find a sangha (spiritual community) and practice.
I myself have a somewhat ADD brain-mind. Though I have, over time, been more and more able to meditate, journal writing, combined with some of the other tools I describe, have been, for many years, my go to personal contemplative and healing practice.
There are many roads to skillful self-presence, many tools to till and nourish the soil of your being. Find one or more and get to work/play and watch things grow and lead you more and more deeply into LIFE/life.
