It's really important to be "selfish". See, the word has a bad connotation, but what "selfish" really means is being in touch with who you are and what you like, what you want to do, and be able to do things based on your personal preferences and qualities. People tend do do actions based on how other people would feel about it, or what they would say. This is not going to bring you happiness. Be connected to yourself, and everything you want will fall into your lap with little to no effort.
