Great Time Waster and that Sucking World

I am learning about diamonds. No, I totally don't know why I need to know about them. They look very concocted to me. I learn them in blind faith that they will be key encapsulating concepts to simplify the view. So far I don't understand nor have I formed any intuition. I know I will understand in finite amount of time if there is somebody to guide me through the labyrinth. I don't know what pieces I am missing.

Then I will need to travel to that world and people gave me the rich idea of downloading Youtube videos on how diamonds are used so that I could still learn on the move. Then I wasted half an hour looking into how to download Youtube videos and another half an hour complaining here while all this time could have been used on just watching Youtube legitimately. That world sucks.
