What do you wish that everybody knew?
People don't learn by reading profound snippets of wisdom. They learn by experience. Then once they've learned, the snippets of wisdom seem profound. The snippet is just a pointer to some amalgamation of experiences that the writer has, and it seems profound to the reader only if the reader has similar experiences to assign it to. If you want to actually share your wisdom, try to share the experiences themselves, not pointers to the experiences. It's still unlikely to work - the reader almost certainly needs to have the experience, not read about it - but it's an improvement.
