Is it wrong to be a "people pleaser"? What is wrong with pleasing others? To what level should we care about others, and what should we avoid?
This is an important topic.


  AN4.95:1.1: “Mendicants, these four people are found in the world.  What four?


There are those who practice to benefit neither themselves nor others. It creates no benefit. Let's skip that one. 

And one can practice to benefit oneself. Or one can practice to benefit others. However...


  AN4.95:3.3: But the person who practices to benefit both themselves and others is the foremost, best, chief, highest, and finest of the four.


Notice also that there is an important difference between pleasing others and practicing for their benefit. For example, a drug addict would be pleased to receive free drugs, but it would not be to their benefit. Let us all practice to benefit others as well as ourselves.
