The only thing one 'should' do is find out who you are, and then Be that!
Everyone has their own unique Nature and everyone should follow that.
find out what you like and what you don't, if anything; Play around with your own thoughts and emotions because their YOURS and No One else's! Pay attention to your Senses for the same reason! if you want to really Feel and Know you're Alive, the only way you can do that is to Fully take in the immediate experience of being your Self.
