We all carry weight.
To think that those who succeed in their desired life’s endeavors are free of any burdens is misguided.
The self-control to be focused, and shutting out general societal constraints, while finding the powers to motivate themselves rather than be herded by those whose job it is to motivate the masses, is not easy to overcome, and that is why it can sometimes be a lonely path.
There is no life that is absent from darkness.
Those that choose to let go may endure more scars from the lessons, but are willing to still go on to the higher level while those below look up and worship in the achievements, not understanding that they too, have opportunities if they choose to strengthen the muscles of their wings need to help them fly.

Letting Go -- from Illusions by Richard Bach
-----------
Once there lived a village of creatures along the bottom of a great crystal river. The current of the river swept silently over them all -- young and old, rich and poor, good and evil -- the current going its own way, knowing only its own crystal self.
Each creature in its own manner clung tightly to the twigs and rocks of the river bottom, for clinging was their way of life, and resisting the current was what each had learned from birth.

But one creature said at last, "I am tired of clinging. Though I cannot see it with my eyes, I trust that the current knows where it is going. I shall let go, and let it take me where it will. Clinging, I shall die of boredom."

The other creatures laughed and said, "Fool! Let go, and that current you worship will throw you tumbled and smashed against the rocks, and you will die quicker than boredom!"

But the one heeded them not, and taking a breath did let go, and at once was tumbled and smashed by the current across the rocks.

Yet in time, as the creature refused to cling again, the current lifted him free from the bottom, and he was bruised and hurt no more.

And the creatures downstream, to whom he was a stranger, cried, "See a miracle! A creature like ourselves, yet he flies! See the messiah, come to save us all!"

And the one carried in the current said, "I am no more messiah than you. The river delights to lift us free, if only we dare let go. Our true work is this voyage, this adventure."

But they cried the more, "Savior!" all the while clinging to the rocks, and when they looked again he was gone, and they were left alone making legends of a savior.
