Critical thinking 

 a. Have you made your own precept after you read this lesson? What is it? Share it with your friends. 

= Precept is a rule or principle that we make to conduct our behaviour on the accordance of that. I also had many precepts even before reading this lesson. The major precepts of my life are: 

"Anything that happens, happens for good", 

"Always stay Positive" 

" Believe in Karma rather than fate" 

" What we are today is the result the choices we made yesterday, so we have to make choices wisely"

= Critical Thinking is the biggest blessing that everyone wants. If someone has the skill to think creatively, she/he is sure to get name/fame/ and money. Creativeness brings the most out of someone. It brings newness, unqiueness and better ideas. From Handling any situations skilfully, communicate with people in a logical manner, to writing books, stories that everyone likes and interested in, Creativity is the one that matters. 

Josh Lanyon has said this very finest quote which I personally liked very much. Creativity enables us to more freely and innovatively examine and resolve issues. Creativity expands up your thinking. A civilization that has lost touch with its creative side is a society in which generations may be closed. It expands our prospects and may assist us to overcome obstacles.

In Nutshell, Creativity encourages group thinking.

Creativity fosters ideas.

Creativity promotes resilience.
