SO TRUE! But be careful what you think about. Here's a suggestion: "Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things." Philippians 4:8
Good to set limits to protect from "takers" in all areas of life but especially if you are the responsible informed legal even hands-on caregiver. You need to learn to set limits to protect yourself from exploitation and intrusion by others to ultimately protect the one for whom you are caring.
