When we carry around regrets from the past, we are living in the past. The past is the past. It exists only as a memory. The past is not where life is happening at this moment. Life happens in every moment in the present.
Be kind to others. Have the courage to say, "I Love You." Give away Hugs as if today was your last opportunity to do so.
Live each day as if it were your last day on earth in the physical body and you will have no regrets.
I wish you much peace.
Many Blessings to You!
