Self reflection is a great grounding exercise. Living in the moment imo should not require too much effort if you are stepping into the next from a good place.

All of our yesterdays make up who we are at this moment in time. Follow your heart and you will be where you are supposed to be when you get do there. Hopefully more wiser.

There is no sin in thinking of the future...and it's ok to look back...just try not to stare as you may not see what opportunity lies in the now that, inevitably, takes you towards your goals and/or those un-imagined to this point.
