The heart of wanting to express yourself, express something mysterious that you feel, is communication with other human beings--at-one-ment with being human. Writing poems alone in your room can only get you so far, the satisfaction is in knowing that other people feel the mystery and passion that you feel. Even for Emily Dickinson it wasn't enough just writing poems. She wanted them to be read, most likely got a couple dozen in print, and shared her poems throughout her life with mr./ms. mysterious.
If only Lenin had understood this before October 1917, Seriously.
By making something purely for the pleasure of others means leaving self out of things BUT it garners more positive feedback. Does that even make sense? For now I'm happy where I am along the path, writing to suit me but happy it suits others too, and being prepared to revisit a work to see where it might be improved if others suggest it rather than thinking 'this is great, if they don't like it, that's a problem on their part'
