What less traveled paths do people follow in life, as mentioned in "The Road Not Taken" by Robert Frost?

People have to choose between a number of different paths in their lives. Some people must choose between doing something they love (one path) or doing something that will pay the bills (another path); sometimes those two things do not coincide. Some people must choose whether or not they want to have a family or how big a family to have; financial considerations often play into this decision as well. One might prefer to have a large family (one possible path), but may make the decision to have a smaller family due to financial concerns (another possible path). Further, one might have to make a more general decision, applicable in so many circumstances, about whether to do some unique thing that they really want to do (one path) or do whatever is considered more socially acceptable or responsible (another path). Some must choose whether to break a law they feel is unjust and accept the consequences (one path) or abide by the law they find unjust and deal with their conscience (another path).
