We choose to break down our individual goals into 4 categories: Spiritual, Physical, Relational, and Professional. A spiritual goal could be to memorize a verse a week, physically you could run a half-marathon, relationally you could organize a reunion with family or college friends, and professionally your goal could be to apply to 5 different jobs that have a shorter commute or buy coffee for your co-workers 1 x a month. Even simple goals can be challenging, just make sure they're measurable!
As far as marital goals go, Tim and I break these down into 4 categories as well: Spiritual, Physical, Relational, and Financial. Perhaps someday we'll simplify our goal categories to just Husband / Wife, Dad / Mom, and friend. But for now, a marital spiritual goal could be to pray with your spouse each night before bed, physically you could compete in an adventure race together (btw, physically can also mean setting intimacy goals), relationally your goal might be to have a different couple over for dinner 1 x a month, and financially it may look like establishing and following a budget or giving X amount more than you gave away last year. Either way, your marital goals should stretch both of you. If they're too easy, you're not challenging yourself enough.
Overall, our main advice regarding goals would be to write them down. Only 3% of people actually have written goals. If you write them down you're much more likely to follow through with them. Also, victory comes with accountability, so be sure and share your goals with friends who will encourage you to follow through with them!
Lastly, always remember the purpose for setting goals is to be transformed by them in the process. What they make of you is always far greater than what you actually achieve!
