I am self driven. I am self propelled. Nature gave me the guts I was born with.

I am self driven. I am self propelled. Nature gave me the guts I was born with.
I know what I need. I know what I want. 
I don't need anyone to tell me how I feel, what I need and what I want.

I find this to be true of all of the life forms I have witnessed during my life.
We know what we need. We know what we like. Simple as that.
