I don't know everything and you probably don't either. But when I'm sure I know something, I don't often put it through this test. Let's say I know TRON which I'm invested in will "moon" eventually. Here's how to review that:
Am I willing to experience the pain &/or discomfort of it being false? No, then I don't know it's true.
If yes, have I moved through this pain &/or discomfort enough to examine it fully? No, then I don't know it's true.
If yes, do I have all the essential facts on it? No, then I don't know it's true.
If yes, can I validate these facts in any way, shape or form? No, then I don't know it's true.
If yes, do I have first-hand experience of any of these facts? No, then I don't know it's true.
If yes, does anyone else I know personally have first-hand experience of any of these facts too? No, then I don't know it's true.
If yes, it's probably true based on what I know for now, however given there's so much I don't know, I'll need to remain open to the fact that with more experience &/or information I may discover it's probably false.
If I'm honest, my truth didn't even pass the first point. All my investment in cryptocurrency I put in TRX, why? Just went with a hunch. But now I'll feel like I really screwed up if it just flops or let's say never picks up.
That's emotionally painful. I'm not sure I can say I'm prepared to feel that, it feels better with some pseudo analysis and wishful thinking keeping that stuff rammed down the feelings bucket.
I can't control the world.... Luckily!
