In the seeing of who you are not, the reality of who you are emerges by itself. (Eckhart Tolle)

Quotes from the Tao Te Ching on holding nothing back in life and on changing the world

“He holds nothing back from life;
therefore he is ready for death,
as a man is ready for sleep
after a good day's work.”
-Tao Te Ching, 50

This does not mean to exhaust yourself, to force things or to interfere; rather, just the opposite. Consider the text that comes just before this:

“The Master gives himself up
to whatever the moment brings.
He knows that he is going to die,
and he has nothing left to hold onto:
no illusions in his mind,
no resistances in his body.
He doesn't think about his actions;
they flow from the core of his being.”

To hold nothing back is, therefore, to flow through life with a heart and mind as open as the sky; instantly and fully accepting everything that comes and goes without resistance. This is the undoing of illusion, the settling toward truth, the experience of ongoing joy and the alignment with true strength.

“When nothing is done, nothing is left undone.
True mastery can be gained by letting things go their own way.”
-Tao Te Ching, 48

We may believe that we have the power to change the world—and that it can be done through attacking evil, by not accepting that which feels wrong, by not forgiving the wrong-doers, by judging, by hiding our true selves and by conforming. This is weakness.

“Do you want to improve the world?
I don't think it can be done. The world is sacred.
It can't be improved.
If you tamper with it, you'll ruin it.
If you treat it like an object, you'll lose it.”
-Tao Te Ching, 29

The problem is not that people don't care enough to save the world; rather, the problem is that too many people are messing things up by believing they can.
