When you enter into a commited relationship, you really have two choices... you can challenge each other to grow or get lazy together as a couple.

I'm not saying you have to get crazy and start rock climbing or bungee jumping. But settling for endless nights on the couch watching TV isn't the best alternative. Instead, write some goals together. They say people are much more likely to accomplish stuff when it's written down.

So see each other as built-in motivational coaches and you'll grow as a couple. That will make your relationship that much more rewarding.
