Love this! It's the story of my life, lol. Like the other comments have already stated, this is a small poem that packs a big punch. It's a life lesson in 9 lines, which is amazing, within of itself. It reminds me off all of the times I've said this to myself but failed to follow through. I think I should favorite this, so I don't forget this time. Great job!
I totally agree with the comments above this one, your poem is very simple but powerful. I am sure that any friends would appreciate a friend like you. I love the ending because it says to me that your friendship is so important to you that you place it above your own needs.
