as someone pointed out before me, the answer is within yourself. this matter is one of the most personal aspects of all creative endeavours. your instincts are fine - you admit to yourself when you feel that you took the wrong turn. just keep on looking and listen to your inner voice, glide on the stream of consciousness.
for myself, it took me some time, but finally i found out i'm interested in the connections between land, mythology and the apocalypse - as strange as it all sound, i embrace these ideas with my heart an soul, because they are truly mine.
