You don't need a special day to celebrate your marriage. Dress up and enjoy everyday. Make plans to keep your life exciting. Ever sit back and wonder why 'they are always doing things'. 'We never do anything' Why are they having fun...'
They are making their fun and you have to make your fun too. What you do with your time is up to you. Get out there and make it happen. It doesn't take tons of money, just a little planning. Maybe you and your significant other can take turns doing the planning and have fun.
