Dont know exactly. Invented that thing.

I start questioning to my mind inside if I see anything and it goes on until I make my mind to stop it forcefully and if I convince my mind with right answer then also it goes on. i.e if I see my friend to watch something on youtube, I would start asking questions to my mind like how easy he is able to explore favourite things on device, in past there was no device like that then also people lived and we rightnow using it as someone has invented. So why we don't invent thing and use that instead using things that is made by others. And same thing happens with learning also like why I should learn X thing as it was not exist before someone wrote it and someone could write and someone has invented. Means why we should learn thing that someone has invented and why don't we invent our own thing nd read/learn that and why we have to learn things that is written by other nd invented by other throughout life. And question comes in mind like how inventor have invented that thing.
