| Overview: Problem-solving is the most widely-known and widely-used application of thinking skills. Problems can be any situation where we are prevented from moving forward or reaching our goals. They may be little niggles or major stumbling blocks which stop us dead in our tracks. Problems are caused by lack of information, lack of insight or lack of ideas. For many, a problem is a reason to give up. But for those with thinking skills, a problem is a challenge to be overcome.
