I had seen sometimes people are worried towards their brainstorming ideas. They knew they can work for their lives and can make them different person. You know, they don't share ideas or don't borrow any help from people, not that they want to go ahead, but it is their ego, i think. They want to over take others. Ego can't see big picture and will never be able to do it. When i see this i feel somewhat bad in my heart. People do you think, is it their ego? or something else? like their conservative mind, which contains lot of narrow thoughts.
