In the strict sense of the word, very few things are “necessary”.
Outside of food, water, shelter, and sleep, we can survive without most of the elements involved in our day to day experience.
Kissing isn’t “necessary.”
Music isn’t “necessary.”
Art isn’t “necessary.”
Dancing isn’t “necessary.”
Sports aren’t “necessary.”
Philosophy isn’t “necessary.”
What does that prove?
It proves that when it comes to doing what you love, necessity isn’t necessary.
The world will not self-destruct if we refuse to do what makes us happy, but following our bliss isn’t about saving the world, it’s about following our bliss. And we don’t need dramatic reasons for following our bliss.
We are completely free to orient our lives around creating the results that matter most to us EVEN IF we can’t prove to others that those results are “necessary.”
At least that’s the way I see it.
