I think different people have different moods and might change their attitude toward you according to their spirits. On some days, they like others, and on others, they are numb or negative. I honestly don't think we live in an age where people like or dislike each other but rather enjoy a single conversation with someone and then move on with their struggles. Relationships are becoming moody, and most people nowadays like or enjoy people who listen to their problems or help their self-interest. Being always kind and helpful is a good thing, but I don't think you have to worry about everyone liking you 😊
