Life isn't like a train ride

For men and women who have accepted the reality of change, the need for endless learning and trying is a way of living, a way of thinking, a way of being awake and ready. Life isn’t a train ride where you choose your destination, pay your fare and settle back for a nap. It’s a cycle ride over uncertain terrain, which you in the driver’s seat, constantly correcting your balance and determining the direction of progress. It’s difficult, sometimes profoundly painful. But its better than napping through life.
