Appearance, talent, personality.

Are they all determined and given to us at birth, things we could not choose and have no control over changing?

The human body has organs with various functions, such as skin, muscles, bones, blood vessels, nerves, brain, heart, and liver, all made up of cells. 
At the center of each cell is a membrane-encased mass called the nucleus.
Inside this nucleus are chromosomes, which are shaped like rods.
DNA makes up the chromosomes.

I know that we are just following what we can see as far as we can, but when you learn about it in science class, it is a very simple sounding structure.
Its form is so beautiful that you wonder if someone designed it, and it is somewhat exciting to think about. 

However, regardless of who designed it, I believe that there is nothing that cannot be changed in a given situation. 
I think it is important how we accept and interpret reality and choose our actions, even if we cannot go as we wish from the beginning.

There are always rules and restrictions in every world, but it is you, and no one else, who decides what to do with the choices you make. 

You can do whatever you want.
You are the one who decides.
