Some people refer to the paths in life as a metaphor for the choices they make in life. For example, to illustrate, imagine walking along a path. At one point in the path, the one path becomes two. At this point, one must make a decision: go to the left or go to the right. To the right, the path is grassy and flowering. The path to the left, on the other hand, is covered with briers and thorns. A decision, or a choice, needs to be made. Take the easier path or the more treacherous one. The decision can be more difficult than one may initially think.
The path to the right seems welcoming, easy. The path to the left seems far more dangerous, harder. Therefore, a decision needs to be made: take the easy way or the hard way. Sometimes, the easy way is simpler, but, other times, the path may be easy because nothing is learned. The other path may be more difficult, but one learns much more by facing challenges head on.
In the end, a path can be used to represent the choices on makes in life--in essence, to go to the right or to the left. This is a choice one must make.
A wonderful poem which speaks to this idea is Robert Frost's "The Road Not Taken." You can read it,and a summary of the poem, by following the links below.
