The way I understood it is that you are first and foremost responsible for your own happiness. No one else is going to be responsible for your happiness, and at the same time other people’s happiness comes second to yours.

Now at first that might sound selfish and borderline “fuck you I got mine”. But I think the message is more “you won’t ever be happy if you don’t look into yourself, see what it is that is preventing you from being happy, and working to change that before you can do anything else, for yourself and for others”.
