I heard this said that having more is never enough. This hit me hard. I say to myself all the time that if I could just have more of ______ then it would be all I need, it would be enough. I have slowly realized that more never becomes enough, it never becomes satisfaction, it never becomes contentment. Have you ever thought about what makes you content? Have you ever said if I achieved this I would be content? Why do we have the idea that being content is something we have to obtain or earn. Can't we just be content.
In Phillippians Paul writes about his contentment;
11I am not saying this because I am in need, for I have learned to be content whatever the circumstances. 12I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. 13I can do everything through him who gives me strength.

This leaves me to believe that Paul learned to be content through everything by learning to rely on Christ through everything, by realizing that Christ is more than enough for any need we may ever encounter. Paul says he can do everything through Christ. If we can do that, then we may learn what it is to be content.
More is never enough, but Christ is more than enough.
