Listener question: uniqueness

I was wondering if you could follow up on your recent Podcast about 'Who are we' to talk about what makes us unique?  

Fundamentally we are all the same awareness, intelligence & energy made into form but what about personalities, preferences and skills?  People in reality can seem very different - some people are more analytical and scientific whereas others are naturally creative or good at practical things.  Where does this conversation sit with nature v's nurture?  I like the idea that we all can do anything if we practise enough and that our abilities aren't fixed but how similar or different are we really?
