Is this really news? I person's personality and condition of the heart will emerge in the natural course of their daily pursuits.
The same can be said of church choirs, basketball teams, and home construction. There are those who are driven to excellence, striving to the limits of their talents/capabilities. Others are consumate team players - encouraging others and jumping in to fill a need. Some are loners, others thrive in group settings. There are folks who crave attention and affirmation, and there are those who are satisfied accomplishing what they're set out to do with little fanfare.
Anyway, to the point, I agree with the premise. My riding follows my personality and particular bent...
