The three vaccines of boredom are all healthy virtues in their own right: Contentment, Imagination, and Awareness.
One of my strongest but weirdest views is that boredom is a character flaw. I think that boring people are bored. The ability to simply exist without needing external stimuli is deeply underrated, and your life will absolutely be better if you cultivate it.
Choose to be content. Recognize that simply existing is marvelous, and that you’re never very far from the next exciting turn in your life’s journey anyway. Enjoy the space between moments, use it to enhance their flavor, instead of desperately trying to fill every gap with some meaningless trinket posing as a real experience. Be comfortable being alone with yourself.
Use your imagination. You have a vast machine for creation within your mind, and letting it atrophy from misuse is a terrible disservice to yourself. In the times without excitement bombarding your senses, explore your rich inner self. Conjure fascination, consider new ideas, or simply have a pleasant daydream.
Work on truly being aware of the world you’re in. Observe the small details, take in the richness of the tapestry all around you. How can you be bored when the sunlight plays among the blades of grass, or the wind moves each of the fine hairs on your arm differently? Microscopic miracles pervade, waiting to be relished.
The dependency upon crafted channels of entertainment and engagement is a curse best broken, and swiftly. Boredom is a rejection of the wonder of our world and your own soul, and I decry it.
