You

3 fundamental things make you who you are:

1. DNA
 

Inherited from your ancestors, produced by evolution. The physical, mental, and behavioral traits that survived, and reproduced in your family tree.

2. Environment

The family you were born into, the culture you were born into, and the time you were born into.

3. Choices

The choices you have made, and are making. Driven by the physical, mental and spiritual stimulus from your environment, produced by thought, will, and action.

Thought - produced by chemical reactions in the physical brain, driven by will and environmental stimulus, and organized by recalling experience.

Will - drive originating deep within one's core, produced by DNA.

Action - driven by will, and directed by thought
