Jesus taught to put others first: Looking out for the good of others

1st Corinthians 10:24 | Don’t be concerned for your own good but for the good of others.

What does being concerned about your own good mean? What does this look like?
Why does Paul tell us to be concerned about the good of others? How is this done?
How does looking out for the good of others show them love?
How often do you make choices based on what is good for others, not just yourself? What can you change to love others better in this way?
