Amateur vs Professional Photographer

I was reading an excerpt from my online PPA (Professional Photographers of America) magazine, regarding light and I really loved this quote.  I have heard and read this so many times from other photographers.

The photographer who says she doesn’t work with strobe, generally means she doesn’t have the skill or is unwilling to expend the effort required to meld strobe seamlessly with other existing light. Lack of skill is not a style. The boutique photographer knows there is no excuse for poorly lit, contrasty, blurry or noisy images unless she has chosen to use these devices to visually enhance meaning.
