Contentment in vocation

I'm looking for Bible passages about contentment, specifically in what could be described as vocation. It seems all my life, I've been looking forward to another phase of life. When I was a kid, I wanted to grow up and have a family, now, I want a time without small children. This general discontentment seems to go through everything. What are some Bible verses I can read when I need a good reminder that where I am is where I need to be?

How about if I refer you to an article that contains numerous Bible passages on vocation? The article is “Understanding our Calling: The Doctrine of Christian Vocation in the Holy Scriptures.” This link will take you to that article. The article will provide reasons for contentment.

Here is a preview: “Work that looks ordinary actually reflects the working hand of God that provides and cares for people. God loves work. ‘In the beginning God created the heavens and the earth’ (Genesis 1:1). ‘By the seventh day, God had finished the work he had been doing, so on the seventh day he rested’ (Genesis 2:2). The joy of work is passed on to Adam, the crowning glory of his creation. ‘The Lord God took the man and put him into the Garden of Eden to work it and care for it’ (Genesis 2:15)…The Christians who see their lives hidden in Christ and seated with Christ in the heavenly realms (Colossians 3:1-3) treasure their earthly callings in a real world of dirty diapers, freeway commutes, group meetings, customer complaints and spreadsheets.”
