From an early age I didn't buy into the value systems of working hard in a nine-to-five job. I thought creativity, friendship and loyalty and pushing the boundaries of what was acceptable was much more interesting.

I'm single, footloose and fancy free, I have no responsibilities, no anchors. Work, friendship and self-improvement, that's me.

Life would be infinitely happier if we could only be born at the age of eighty and gradually approach eighteen.

Probably the happiest period in life most frequently is in middle age, when the eager passions of youth are cooled, and the infirmities of age not yet begun as we see that the shadows, which are at morning and evening so large, almost entirely disappear at midday.
