Fitkid, do you have all your senses together?
Don't fall into any blind followerships. Do your own thinking. DYODD. We all make mistakes, and we should all be humble. And, nothing is 100% guaranteed, even if certain people tell you so. Maybe 99.99%, but not 100%.
The essence of this universe is that nothing is certain. The moment of decision is the present. Decision is free will, and free will is not predictable because otherwise it would not be free. In other words, existence is equivalent to decision is equivalent to free will is equivalent to randomness.
So, don't give up your free will.
... and embrace uncertainty.
