What is important in life. What gives us a life of meaning, a life of fulfillment.
I would say it is the experiences that give life meaning. It is the experiences that cause us to grow and learn that give us fulfillment.
When you first contemplate what experiences you want in life you tend to think short term (short term for experiences). You think of those experiences that are on your bucket list. Places to see, things to do that are on your bucket list are usually things that you would want to do once but then would get bored of doing the same thing over and over again. You would realize that you want experiences that cause you to grow or to learn a new skill. Learning how to ballroom dance is an experience that will give more meaning and fulfillment to your life than seeing a new tropical vacation place.
Once you come to this realization you can start to contemplate experiences that you are drawn to, that you could learn from, and that would force you to grow. Seeking out these experiences will open the doors for other bigger experiences.
Once you know the experiences you want in life, things become possessions that make your journey easier and more enjoyable. A nice car to get you to dance class makes the whole experience more enjoyable. And there is nothing wrong with enjoying a fulfilling life that is helping you to grow.
