Develop the gratitude attitude
Having people list three things that they are grateful for in life, or three events that have gone especially well over the past week, can significantly increase their level of happiness for about a month. This, in turn, can cause them to be more optimistic about the future and improve their physical health.
Visualize yourself doing, not achieving
People who visualize themselves taking the practical steps needed to achieve their goals are far more likely to succeed than those who simply fantasize about their dreams becoming a reality. One especially effective technique involves adopting a third-person perspective: those who visualize themselves as others see them are about 20 percent more successful than those adopting a first-person view.
How To Praise Children
Some praise can have devastating effects on a child's motivation, while other praise can help them achieve their very best. Telling a child they posses a certain trait, such as being bright or talented, is not good for their psychological health because it encourages them to avoid challenging situations, not try so hard and quickly become demotivated when the going gets tough. In contrast, praising effort encourages people to stretch themselves, work hard and persist in the face of difficulties.
Detect a lie
When lying people tend to think hard (because they are trying to remember what you already know and what you don't) and become more static and use less gestures. They also tend to distance themselves from the topic by using "I", "me" and "my" less often.
It is a myth that when lying people become anxious and get sweaty palms, etc. Instead they start to think harder and speak slower.
