The scariest thing in life is if you are not able to fulfill your destiny.
Two things come in the way:
First, knowing what’s your destiny.
Second, are you still not so far away to change your path to fulfill your destiny?
For some, you can’t find your destiny and hence never achieve it.
For some, you find your destiny and achieve it, even if it’s in the latter part of your life.
Most of us, find our destiny but can’t change the path or don’t want to risk changing the path.
