I'm a writer and a philosopher, and the qualities you need are:
the ability to see beyond the normal,
to understand that much of who you are now is the result of society's influence on you and not because of what nature intended,
to learn how to organize your thoughts,
to have a great imagination and the courage to be different,
to not let censorship and society's propaganda restrict you from writing what you want, or being who you truly are,
to make full use of your dreams and nightmares to gain new inspiration,
to explore a wide range of philosophical topics and not be only limited to a few,
