Robert Frost stuff

I read "The Road Not Taken" in a literature class in about 8th grade and hated it. I thought Robert Frost was a complete sap to focus an entire poem on an itty bitty decision changing the outcome of life and potentially regretting it. My thoughts were along the lines of "You can't change the past. Why bother focusing on one little decision so much?". Obviously, I didn't read the poem very closely in the first place and it certainly wasn't explained to us. Now that I have a better understanding of the poem, I no longer feel like it or Robert Frost should be held in contempt. It seems to me that Frost is really suggesting that some decisions really don't matter much either way, even though we will probably look back upon them and (perhaps erroneously) think they changed our lives. By no means do I think our decisions don't matter or don't have consequences, but, realistically, we have to make decisions and we can't make a big deal over every decision we have to make. I hope this all kind of makes sense.
