Focus on quality.
Instead of eating an entire candy bar, have one piece of really good chocolate.
Choose fewer pieces of high-quality, beautiful, classic styles instead of blowing your entire wardrobe budget on the latest trend.
Instead of trying to visit every landmark when you're on vacation, choose a few and spend some real time there.
This is important for relationships, too. My Sweet Hubs and I have learned that we do better if we work separately during the day to get our respective chores done without interruption, and focus on each other in the evening. As much as love him, I really just don't get as much done when he's in the room. It's much better to get the work done and be able to focus completely on each other later.
