"Wise men say, only fools rush in" a beautiful song. Your title remind me of it.
It is not true that only wise can predict market and take profit. Everytime conditions are different and decisions should also be different and that's why even knowledgeable also fail to catch it.
Without worring about financial gain or loss , it is good to value family first and then profitability. I salute your remark about relationships, time etc. as at the end the day money doesn't go with us. 🤣
There is the knowledge, and then there is the application of the knowledge. I think the knowledgeable fall down in the application a lot.
