If it is not truthful and not helpful, don't say it. If it is truthful and not helpful, don't say it. If it is not truthful and helpful, don't say it. If it is truthful and helpful, wait for the right time.
Knowledge is inherent in man; no knowledge comes from outside; it is all inside. We say Newton discovered gravitation. Was it sitting anywhere waiting for him? It was in his own mind; the time came and he found it out. All knowledge that the world has ever received comes from the mind; the infinite library of the universe is in our own mind. The external world is simply the suggestion, the occasion, which sets you to study your own mind.
Around every corner is another gift waiting to surprise us, and it will surprise us if we can achieve control over our natural tendencies to make comparisons [to things that are better rather than things that are worse], to take things for granted [rather than imagining how much worse things would be if they weren't there and so feeling grateful], and to feel entitled!
Look what you've already come through! Don't deny it. You've already come through some things, which are very painful. If you've been alive until you're 35, you have gone through some pain. It cost you something. And you've come through it. So at least look at that. And have a sense to look at yourself and say, "Well, wait a minute. I'm stronger than I thought I was."
