Though it is impossible to please everyone, to do so seems at times more feasible than being able to please oneself. Do not be disheartened, though; it is not impossible, even if it may feel like it. All you have to do is identify what it is that is making you unhappy, or preventing you from achieving happiness, and then devise a way to overcome it, circumvent it, or deal with it in a healthy way. A problem always seems insurmountable, but only at first glance; study it more, or get help from others if needed, and you should be able to find a way to get through it.
