The other morning, I was listening to a sports radio station when I heard something that caught my attention. 
One of the commentators was talking about a football player who was in the middle of contract talks, trying to get, like, $16 million next season. He then made what I consider a bizarre statement that this player needed this amount because “after all, he has to feed his family.”
There is nothing wrong with a player making a deal for what they think they are worth — but needing it to feed your family? A statement like this shows an attitude of discontentment.
In the Scriptures, the Apostle Paul says that he has “learned to be content whatever the circumstances.” He went on to say, “I 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.” (Philippians 4:11-12) 
There is nothing wrong with ambition, but during times when things are going our way or in times when they are not, we still can be happy. We still can look forward to another day. 
We can be thankful for what we have, even if that means just having our basic needs being met.
The Bible also teaches us that our main priority should be putting Jesus Christ and His church first in our lives. If we will do that, He has promised that at least our basic needs will be met (Matthew 6:33).
For most of us, we have way more than we deserve.
