I love Arthur Schopenhauer because he made me understand that the world we see in our life is just a Representation of our will to shape it.
The problem is that you must know yourself very well, to have a stronger power of the will to build a bigger World that for him was based on that "subjective" value for many people, Truth
“Life is short and truth works far and lives long: let us speak the truth.”

Carl Jung the master of conscious/unconscious about this post would say
"A man can do what he wants, but not want what he wants."
When an inner situation is not made conscious, it appears outside as fate.
