Discover how astounding you really are:
A short exercise to re-calibrate your perception
Before pondering the pictorial summary above, watch this excerpt from a recent animation that provides just a hint of the unimaginable dynamic complexity that you are (full-length version with narrative here).

Do not buy into your perceptually limited mind telling you ‘this is just what happens in my cells’. Although near the cutting edge of biological animation and still a relatively crude representation of the molecular biology that you are in action, right now, it does begin to reveal what extraordinarily complex beings we are, divine poetry in molecular motion.
Watch it a couple of times and allow yourself to imagine that this is what you are, then multiply the molecular and cellular complexity and transpose that to the structures that play a major role in facilitating our sense of self, our neural cells, when watching this very simple animation. 
Now imagine the aqueous environment in which all this highly sensitive and interactive molecular machinery depends on being completely flooded with extremely reactive biochemistry. The most complex biochemical cocktail in evolutionary history also produced by equally complex molecular machines in one almighty orchestrated molecular dance.
Finally once you to begin to recognise how extraordinarily complex your evolutionary process is then take a look at the simple pictorial summary below and try to see way beyond the ‘trees’ the ‘humans’ the ‘fruit’ etc and imagine a single interconnected molecular organism.
While your brain was evolving it was effectively an extension of the most complex ecosystem we know. Scale that into molecular ecology that involved the plant chemistry reading our DNA and directly modifying the evolution and development of our mind and you begin to realise that we were not and could not be fully functioning once we were chemically separated.
