Look, I get it, you tried something and it helped you, or you’ve seen it help someone else. Clearly, you are excited about the possibility of helping others, but you’re forgetting something. You’re forgetting that the person you are sharing this advice with, isn’t you.
When you come walking into a conversation with friends, or especially into online communities with statements like the ones above, the message you are actually sending is “Gee, fixing this is easy, you’re just doing it wrong”.
Imagine using those actual words towards someone you barely know. You wouldn’t, would you? At least if you’re a decent human being, you wouldn’t. But you are totally willing to take your beliefs, your own experience, and completely railroad another person’s current reality with it, you are doing something awfully similar. In a moment of emotional vulnerability, you have come in, guns blazing, with the suggestion that all of this pain they are in, and all of this struggling they are going through, should have been easy to avoid.
