The biggest key to a happy marriage is being happy with oneself. If you suffer from depression, low self-esteem, grief, and the like, the angst will sully your view of marriage. Take steps to improve your self-esteem if a physician or counselor believe it is languishing. Practicing forgiveness is also a key to a happy marriage. Partners make mistakes. Often! Being able to acknowledge the mistakes, remedy them, and forgive the offender will help nurture the love that’s vital to the marriage. Also, sharing some common ground with a partner – a goal, a hobby, a core value – will continue to breathe levity and joy into the bond.
