Critical Thinking

Hands down the most important skills you have to have are ability to analyze and process information accurately, so that you are aware of the subject you're working on. Second is the ability to break down the information to observe all the details; this will help to find multiple sides of the topic as a may to better manipulate the information as well as understand it's purpose. In addition to this the ability to synthesize the info and compare it with other topics can open up new insights as well which is very important for critical thinking. Using these skills it then becomes possible to reshape the information you started  with into a new form that really demonstrates the ability to think critically.
