 If you haven't used a cup, you wouldn't know how much water it can hold. If you see someone who is shining or someone who is going through a lot in life or maybe someone who is rich and you think they had it easy in life, that is why they are so rich or that is why they are so poor, you may never know the process that led them there. So you have to experience or go inside their mind for them to give you the context.
