Every once in a while tune to a random radio station or tune to a random TV station or pick up a random book in a shop or library. Make this as random as possible without plan as to what kind or genre of book, radio station or TV station. Then you will be maybe, but definitely over time if you keep this practice up, be exposed to something you normally aren’t exposed to. This is healthy and helps us to expand as humans.
Normally we make conscious decisions in what will read, listen to or watch. This means we constantly reinforce what we like or believe we like while rarely seeking things outside. It is good to break this habit.
Of course this idea can be expanded to activities beyond those mentioned above.
