Paved ways

I have to walk through a park on my way to office every day. Small stones were there on walking track of park as remaining of some civil works around. I noticed that most people avoid to walk on tracks rather they were using the sides of track with grass on it. Some people however used to walk on track also. After some days i noticed that due to daily walk of few people there, stones and hurdles were buried or set out of track and now it was more easy to walk on it. It tend me to think that often paths and ways are not easy in our lives but several unsung hero participate to pave them unnoticed.
