Anything can be interesting
Things can be taken in two layers of depth, the surface level and the deep level.
At Surface Level
At the surface level, things may seem uninteresting. Just off minimal observation, we may find things uninteresting if it does not directly concern us.
At the deep level
At the deeper level, anything and everything is interesting. Even the simplest things like the observation of a falling apple (Newton) carries the most indefinite of complexities.
Look deeper and find these complexities, and you won’t be disappointed.
