It was said by Thomas Edison. But what did he mean? In my opinion, it means that in order to have a great idea, you need to have a lot of ideas because many ideas will not be successful. But the more ideas you have, the more chance you have that one of them will eventually be successful. You just need to collect these ideas, it does not matter if one is greater than the other, the point is to have several ideas.
If life finds one of them, it might turn out to be a great vision. Do you have any ideas?
