To re-experience the feeling of surprise, what you need to do is try new things. If life stays the same, of course it will look dull and boring. So I constantly inject fresh vitality into my life. It is more difficult to maintain enthusiasm for things that have been repeated for several years. So I change my schedule from time to time to add new impetus to my life.

Even changes in smiles will have a huge effect. For example, you have run 3 kilometers on the same path every day for the past six months. So starting today, change the path. Or start to learn to cook instead. Cultivate a new interest. Start saving shopping. Explore the local tourist attractions. There is no need for earth-shaking changes, as long as there are differences.
