Life can seem sadistic-teetering on masochistic.
There is no “simple solution” to it.
We feel unhappy with it sometimes because we think we are supposed to be happy in it.
But the truth is, we have to take our joy from it-like a thief in the light…
Happy is a condition.
Joy is the only state of mind that is the state of being.
Whether we realize or accept it as fact, “happy” is a fluctuating and fleeting emotion; contingent upon so many things that ignite it (long or short-term).
But pursue it-intently while remaining gratefully content with where you are and what you already have, and with that-joy will definitely be found.
