Philippians 2:21,22 - They all seek their own interests

2:21

“For everyone looks out for their own interests, not those of Jesus Christ”. This is an example of where “all”, or “everyone” does not mean literally “all” or “everyone”, for Paul knows that there are some good people of whom this is not true, such as Timothy, and various members of the Philippian church. The positive lesson to be taken from this verse is that we should be looking to the interests of Jesus Christ. We should be Christ centred. 

2:22

Timothy had proved himself to be of a different spirit, and the Philippians had seen evidence of this for themselves. Timothy had worked together with Paul for the gospel. And he had done this as a son working for his father. It was not a mere work-relationship, but a heart relationship. They were both focused on Jesus Christ.
