Man is not fully conditioned and determined but rather determines himself whether he gives in to conditions or stands up to them. In other words, man is ultimately self-determining. Man does not simply exist but always decides what his existence will be, what he will become in the next moment.

I think my dad was so fascinated by this idea because he realized
on some fundamental level that he was not in control of his desires:
I think he woke up every morning in his nice house with hardwood
floors and granite countertops and wondered why he desired granite
countertops and hardwood floors, wondered who precisely was
running his life.

With determination, discipline and hard work all dreams become a reality.

Every instinct that is found in any man is in all men. The strength of the emotion may not be so overpowering, the barriers against possession not so insurmountable, the urge to accomplish the desire less keen. With some, inhibitions and urges may be neutralized by other tendencies. But with every being the primal emotions are there. All men have an emotion to kill; when they strongly dislike some one they involuntarily wish he was dead. I have never killed any one, but I have read some obituary notices with great satisfaction.
