Imposing goals ourselves to reveal weaknesses

The Last Samurai
Katsumoto: You believe a man can change his destiny?
Nathan Algren: I think a man does what he can, until his destiny is revealed.

One Outs
Hiromichi Kojima went to a mountain to recover his willpower by chopping a thousand pieces of firewood, but before cutting the last one, a butterfly stopped in the way of the ax and, while he avoided to kill the insect, he got his hand injured. After this, he said "Oh! so, this is my weakness!"

Monster
When Dr. Kenzou Temna was fired because he attended Johan instead of a politician, he complained by saying "What a wasteful life"; but after he decided to continue his life and pursue his dreams, his previous job is given back! Then he complained again: "What a wasteful life".

Berserk
A recurring reflexion of Guts in many aspects is "Why I always notice it when I already lost it?"

If you focus on only one goal and push your life to its limits, you will see more and more obstacles that makes difficult for you to catch your dreams. Sometimes you feel that, as you get closer to your dreams, you start to feel yourself alone, with no one to share your happiness, but a ton of people willing to share your benefits and profits.

Alone with your dreams, or accompanied with no dreams? success or company? Loneliness is a weakness I found in myself. Yours may vary.
