Regret Quotes The bittersweet tears shed over graves are for words left unsaid and deeds left undone. Lost time is like a run in a stocking, it always gets worse. The biggest regrets in life are the chances you never take. I would trade ten thousand tomorrows for just one single yesterday. The past cannot be changed, the future is still in your power. When we fill our hearts with regrets over the failures of yesterday and with the worries over tomorrow, we have no today in which to be thankful. One problem with gazing too frequently into the past, is that we may turn around to find the future has run out on us. You can’t go back, it will never be the same. You can only move forward. Now is not the time to cling to what was, but to amend what is. - Helen Hayes Regret for the things we did can be tempered by time; it is regret for the things we did not do that is inconsolable. - Sydney J. Harris I do not regret the things that I have done, but those that I did not do. Forget regret, or life is yours to miss.
