How to keep your life exciting

There are many things in life that are exciting. A roller coaster ride. Being in love. Winning a game. Watching your favorite show. If this is so, why are so many people struggling with enjoying their lives? Why do so many people get bored so easily? How can we keep our lives exciting?
I believe people get bored easily because they allow their lives to be mundane. They do the same things each day, every day. They have their habits (when they get up, how they get ready, what they eat, etc...). They go to their jobs, do their work, and then go home. So many people live very predictable lives. The older we get, the more we tend to slow down and plan less. Now this isn't true for everyone, but I believe it is true in many ways for those who feel boredom.
How can we keep our lives exciting? I think we can do many things. First, we can learn how be content with what we have. Philippians 4:12, "I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation..." When we are content with our life, even the simplest of activities can be exciting; even cleaning up the dog hair. For me, just being with my kids is exciting; we don't have to do anything special. Second, we should be more proactive in our planning. We don't have to plan something to do every day, but at least once or twice a week would be helpful. If you do this, you have something to look forward to. Maybe it is a lunch with a friend, or a trip to the movies with your spouse, or an outing with your kids. Putting these events regularly in your schedule will bring enjoyment and excitement.
