When we aren't told known truths and are left to find out for ourselves, we might put ourselves in bad situations

Time it consumes is a lot. Like you would be struggling otherwise. Some of the time consuming actions happen because knowledge transfer does not happen. I know I had to learn from a lot of mistakes and nobody explained things. It would have saved a lot of time. I also think that with time the truth changes and we move ahead based on new change in the world.
