What's your motivation to write....

What is your motivation to write and when did you actually discover your writing talents? As a writer of poetry I am motivated by many things: something I seen on T.V., a phone conversation, I even wrote about having a flat tire. I starting writing as a child (roses are red) and progressed over the years. Wasn't till recently that I embarked on the adventure of writing a book and I must say it's been rather interesting.
