This sentiment is one that swells a desire within me for all my friends to pursue the art of writing as well.
Not to have writing done by committee, mind you, but to amplify and enhance the conversation.
The unique world view that each individual holds is squirreled away in their minds, only to appear at infrequent dinner conversations or at passing social engagements. Writing allows one to channel the chaos of the individual mind into a solid form to rub against, to interlock, to resonate, to repel or repulse, to change or be changed by the forms of others. Writing will ultimately enhance by adding to the collective form that we all assume.
So, write! Don't worry. As Kerouac says "just blow and blow."
