I agree with the many other good posts, find your niche, it will come to you.
Though there is also another good saying, "Opinions are like a$$holes, every has one and they all stink."

Not everyone will find a particular fragrance appealing, but that shouldn't stop you from sending it out on the breeze, if you feel so inclined. Speak what you feel -- some will agree with you, some won't. Diversity is what makes life truly interesting, particularly when it comes to opinions.
