Humans and Animals
In the grand scheme of things, we humans are not that special.
We are very similar to other animals in the wild.
Evolutionary mechanisms, fight-or-flight, desire for conquest and expansion, a desire to duplicate our genes, etc.
So before you start reading self-help books, or you start reading philosophy and spirituality in order to try and increase your motivation, learn first to live in alignment with your biology.
I can guarantee you that if you optimize your sleep, your diet, your training and your testosterone production, you’ll by extension become more ambitious.
Ambition is just another word for wanting to expand and grow - just like some animals.
And you can’t expand or grow if you feel like shit all the time.
