I really enjoyed this poem a lot. It has a very strong message I feel. The title goes well with what you have wanted to write as well. I did personally like the "free flow" of the poem I believe it makes the message stronger. There is a small error in the second line that takes away the flow I feel. "You've should be you or walk should be walked" you are saying you have walked life roads. Otherwise I love the message of the poem as a whole. I believe what you are saying is at a certain point in life you feel regret for what you have not done in your life. We follow the wrong path a lot instead of the path that will make us truly happy. Then death occurs or in your older age we look back and regret. Very good write.
