Do you habitually give in to other people because you just can't stand the thought of upsetting them? Do you put your needs to one side because you get a buzz from someone else's happiness, only to find that he or she is not a bit grateful? If so, you are a classic "people pleaser," and you are, in all probability, not getting what you want out of life. It's time to shift the focus from others to yourself, and stop being a martyr.
Hmmm... Purple people pleasers? hehehe....
Seriously, it's hip to be selfish sometimes.
