I think that gravity sets into everything, including careers, but pendulums do swing and mountains do become valleys after a while... if you keep on walking. ↗
East Yorkshire, to the uninitiated, just looks like a lot of little hills. But it does have these marvelous valleys that were caused by glaciers, not rivers. So it is unusual. ↗
The weather was fine, the valleys literally covered with buffaloe, and everything seemed to promise a safe and speedy movement to the first grove of timber on my route, supposed to be about ten days' march. ↗
That ere long, now that curiosity has been so much excited on this subject, some human remains will be detected in the older alluvium of European valleys, I confidently expect. ↗
There are obviously peaks and valleys in everyone's career. This business can be a roller-coaster ride, and it's really hard to stay on top all the time. Very few people do. ↗
