Share Time Together
Don't forget that this is your best friend, your soul mate, your life partner, and your other half. You chose to spend the rest of your lives together, so make sure you spend time every day together, or as often as possible. Hang out. Have fun. Be silly or serious. But doing it together reminds you of all the reasons you vowed to be together "for as long as you both shall live". Fall in love all over again.
