One way that this poem suggests the hardships of life is that the speaker stops in the woods to escape his daily life. He stops to look at the beauty and simplicity of nature. He is away from civilization (people, towns, cities). The piece of land he is looking at belongs to someone else but that person lives in town. He is in solitude, in the midst of the woods.

One way that this poem suggests the hardships of life is that the speaker stops in the woods to escape his daily life. He stops to look at the beauty and simplicity of nature. He is away from civilization (people, towns, cities). The piece of land he is looking at belongs to someone else but that person lives in town. He is in solitude, in the midst of the woods. He is beyond the daily cares, duties, and responsibilities of his life. This is a momentary escape.

He adds that his horse must think it is odd that he would stop and stare at the snow and the trees. The horse is probably used to stopping at homes and villages: not in the middle of nowhere. Some critics suggest that in this momentary contemplation of nature, this temporary escape is actually a contemplation of suicide. If that is the case, it is the contemplation of a permanent escape from the hardships of life. (Frost denied this was the intended meaning.) 

By the final stanza, the momentary escape has passed. While it lasted, the speaker took pleasure in this respite. The woods are "lovely, dark and deep." The "dark" adjective suggests something sinister, perhaps lending credence to the suicide theory. But dark can simply mean mysterious and thereby, full of wonder. This seems to be the more likely intention (according to Frost). He would like to stay in this moment of escape and wonder but he has more ground to cover and more things to do before he can rest for the night ("miles to go before I sleep"). The notion that he has "miles to go before I sleep" could signify things more broadly. For example, it could mean that he will have many more responsibilities (career, marriage, children, etc.) to attend to before he dies in old age (the final "sleep"). In either case, "miles to go" implies actual traveling distance but also figurative notions of responsibilities and hardships during the journey of life.
