A Reason To Live Besides God?

I noticed someone posted the other day, that they cant wait to get to Heaven. That they would be happy if God took them now. But the post was qualified by another later saying "But God needs me to do some more work here on earth, I'm not sure what."
At the moment I have a nice partner and dog. A nice happy home. I feel this is my reason to live. Now, I know, strictly speaking, I shouldn't make them my reason to live. That my relationship with God is the one that is really important. But still I would be devastated if and when they die. I'm only human. I can feel grief. I need someone close to me I can trust 100%.
If heaven is so great I guess I want to be there too but at the moment life is pretty good here and I cant imagine it being much better anywhere else.
We all need a reason to live. My career has been all over the place. A failure in many respects. I certainly don't get my meaning of life from it now. Maybe I never have. But I understand that for some people, their job is their reason to get up in the morning, because they love it.
So I agree with the post a little because would like to know what God wants me to do, for the rest of my life. As long as its not too challenging!
