the tone robert frost constributes to what he thinks about people.
what people want is the easy way threw, but the easy way only leads to rough passages. easy passages only take you to the normal side, like everyone else. he is saying if you break out of your confort zone to go out of your way in the hard passage, you wont be like everyone else living the same thing over and over again. instead, you will be on top of everything and everything will be at your control instead of someone mouth feeding it to you, like the rest of society.
