It sounds like this is sung from the perspective of someone who is "up in the sky" and has to "drop to the ground" to re-enter reality.
My personal interpretation is that this person was pursuing someone and now the possibility of being in a relationship has just become real. So you leave that honeymoon phase and have to address the issues that come with a relationship. You realize you can't keep everyone happy: the person you're dating, your family, your friends... so you just have to live for you, because everyone else has an agenda. It's only you that lives for yourself.
