"Nobody can go back and start a new beginning, but anyone can start today and make a new ending."
Leave the hurtful or sad times in the past. As well as regrets also. You cannot achieve happiness by dwelling on the past. To many people stress about the "would haves" "could haves" & the "If I only did things differently" You can't change the past. It is done. It's over. Plenty of people miss their share of happiness, not because they never found it, but because they didn't stop to enjoy it.
