Color has long been known to be a stimulant. In fact, the color yellow in particular has been shown to entice children (Legos, for example). I think we live in a world where we want fewer distractions and more focus — for several good reasons.

1. Our time on this earth is limited, we need to make the most of it.
2. We can be more productive if we are forced to focus.  Recently, I have totally blacked out the second monitor on my desktop computer so I am forced to focus on one task, but realize that the other monitor is there if I need it. So many apps now have “focus” mode or “Zen” mode or “fullscreen” mode. Take advantage of it. If you’re not too distracted you might thank me… #GrayPhone
