Is destiny pre-written or is the course of our lives in our own hands by virtue of our power of choice?
I believe destiny is the default setting, and choice is our ability to customize.
Life is like a game of cards; the hand you are dealt is determinism; the way you play it is free will.
— Jawaharlal Nehru
It does not matter what one believes though. That would be akin to being concerned about the lock and neglecting the key. The key being acceptance of the situation, regardless of it being pre-destined or brought about by the exercise of our own choices.
What we believe, is of no consequence, if we do not use such belief to achieve the effect it is designed to deliver – that of acceptance of our situation.
Belief is a tool for achieving effects; it is not an end in itself.
— Peter Carroll
Anything and everything you hear from supportive family and friends, read in books or online, or understand through analytical thinking is moot, as those are no more than means to justify to your mind why things are the way they are. They are not solutions.
The bottom line, after you have changed what you can’t accept, is to ultimately make peace with your situation by accepting the culminating product of your choices.
Change what you can’t accept and accept what you can’t change.
