What is the meaning of Mary Oliver's poem called Flare?

This poem covers a range of topics but ultimately I believe the message is that life is fleeting, so we shouldn't dwell. It emphasizes cherishing the present moment, following the example that nature sets for us. It encourages me to observe nature and take in the ways of animals who don't pity themselves or focus on the negative. Those are the things that stick out to me about it, anyway.
