The lasting effects of this practice lead to a more satisfied existence. An existence full of happiness, contentment, and focus. We will spend less time worrying about the future or reliving arguments long since passed. This is poison to our minds. Reliving memories other than to reflect on a lesson learned or an enjoyable time, is like experiencing that reality again. The mind knows no difference.
Do not spend your life with a mind filled with hate, loss, or jealousy. Recognize that these are part of the experience, but you can control what you want to feel, and when. This is the pure power of the mind. Harness the powers of the mind that will propel you into a better life. Remove those habits that do no improve who you are. Observe them first. Know that you are not identical to them. Rise above them. Meditate.
