I think this poem is about what you have to do in life, no matter what is happening in it, i mean you always need to give the best of you, help, be grateful, accept that everything you have in life is great and when you accept that, you'll have better things.

Also i want to say that i thing this poem is more like an advice of what you have to do in your live, to tell you that everyone need to embrace their life and start to do grate things, such as love, give and be the great person that you are definitly meant to be
