I’m struck by the assumption in this essay that you have a clear distinction between your own values and other people’s.
I think that having a clear sense of personal identity can be difficult and not everyone may be able to hold on to their own perspective. I am concerned that this might be especially hard in an era of social media, when opinions are shared almost as soon as they are formed. Think of a blog/tumblr/fb that consists almost entirely of content copied from other sources: it is nominally a space curated/created by “you”, but really it is a lot of other people’s thoughts aggregated with very little personal modification. That could be a recipe for really poor internal coherence.
It’s pretty standard psychologist’s advice to have a journal where you write truly private reflections, shared with literally nobody else. I imagine this helps in constructing a self with boundaries.
Relatedly, “self-affirmation” (really kind of a misnomer: it means writing essays about what values are priorities for you) has a large psychology literature showing lots of good effects, and I find it extremely helpful for my own thoughts. A lot of self-help seems to boil down to “sit down and write reflections on what your priorities are.” Complice is this in productivity-app form, The Desire Map is this in book form, etc.
