Most of us tend to be in a hurry to get to the next thing or reminisce to the past. We do it so often that I do believe that we get something doing so.
It is your Ego that gets a rush going into the future or the past. These trips into the future or the past feed the Ego. The Ego does not gain anything in the present moment.
If you want to feed your Core Self, stay present. Bring all your attention to whatever that you are doing and you will realize your Core Self. It is the Power of Now that illuminates your Core Self.
