Are you constantly comparing things to the past when trying to do your best for yourself, your family and your marriage? If you're constantly trying to measure up to the past, Dr. Robin says you're not really focusing on achieving your best in that current moment.

Instead of trying to clone—or even exceed—a moment from the past, allow the gift of the present moment to give itself to you, Dr. Robin says. "If you spend so much of your time pushing and resisting this moment, you actually miss out on living what life has to offer," she says. "It's about allowing this very moment to be its own."

Don't cling to the past, Dr. Robin says. "Let this very day and this moment be yours," she says.
