It's always too early to quit.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
If you're going through hell, keep going.
Quality is not an act, it is a habit.
The most effective way to do it, is to do it.
Begin to be now what you will be hereafter.
If you've got a talent, protect it.
Be thine own palace, or the world's thy jail.
If you can dream it, you can do it.
That something extra, I believe, is a certain humanity that comes from upbeat and positive human interest letters and success stories. Advertisers like to be associated with those qualities.
