Wonderful lighting adds an energy boost when I crochet. I was in the laundromat the other day with my crochet and I didn't want to leave there. Soon I figured out that it was the overhead lighting that made the difference. My home has poor lighting which sometimes affects my crochet work. If you live in a sunny place then you're in a good place to crochet. Also, white yarn is another boost over a deep color like red or purple. With the red yarn it's harder to see what you're doing whereas with white I see much better.
