What does the bible say about our motives and intentions

Each of our actions is driven by some motive or goal and is in a way benefiting us. Every act of generosity or charity also benefit us somehow, I do not think that it's bad, only when we are not glorifying God in our actions or thoughts or when we put conditions to our acts that I feel it would be better to not even do the generous act in the first place. Thus said attached is a link of bible verses that speak on motives and intentions.

The next time you do something, evaluate your motives and ask yourself, I'm I glorifying God solely or I'm I doing this to be praised. Galatians 1:10 For am I now seeking the approval of man, or of God? Or am I trying to please man? If I were still trying to please man, I would not be a servant of Christ
