For a person who is seeking happiness from autonomy, if listing three things as the most important in one's life, it would be oneself, profession, and love. Everything outside can be rebuilt according to those three. Self determines what kind of person you will be; profession determines how wide your own world can be; lover determines how happy you can be.
A profession means delving into something you’re passionate about, and one can make it their own system over time; in other words, it must be self-research-based. More importantly, it won’t be taught; it must be driven by themselves.
Therefore, such a process for a profession can also be a self-methodology for other things. It’s universally applied. The outcome of a profession represents everything, meaning a person’s values are inevitably reflected in their work.
