I think about this poem when choosing a advanced class...

Two roads diverged in a yellow wood,  And sorry I could not travel both  And be one traveler, long I stood  And looked down one as far as I could  To where it bent in the undergrowth; 
Then took the other, as just as fair,  And having perhaps the better claim,  Because it was grassy and wanted wear;  Though as for that the passing there  Had worn them really about the same, 
And both that morning equally lay  In leaves no step had trodden black.  Oh, I kept the first for another day!  Yet knowing how way leads on to way,  I doubted if I should ever come back. 
I shall be telling this with a sigh  Somewhere ages and ages hence:  Two roads diverged in a wood, and I—  I took the one less traveled by,  And that has made all the difference.
