If you aren't satisfied with where you are at the moment, you need to invent your own destiny.
Feeling unfulfilled at work? Volunteer after work. Or start writing. Or singing. Or knitting caps for soldiers overseas. Or training your dog to do a new trick. Or find a new job that does get your motor running.
Marriage seems blah? Take charge of that and do something to liven it up. Buy a red lacy corset and a bottle of wine. Do something unexpected. Don't wait for your spouse to change it up, to romance you or act better or whatever. Set it motion for yourself.
