In my opinion, thinking out of the box is challenge for everyone. It depends on what you think and how much you think different from other people. No one can decide that your idea right or wrong because we have the freedom to thinking. Actually, thinking out of the box is the way to create or develop new things that may cause in the world. If we can practice thinking skills and develop ourselves to be a person who has the ability of creative thinking, problem solving, working or management, it will cause the higher effectiveness in our life.
