Success and failure

Following the principle "success nourishes self-esteem" has led some researchers to the question: Is it possible to raise self-esteem and promote achievements through positive "messages" like "Well done!", "You will do it!"?
The researches have confirmed that indeed, low self-esteem sometimes creates problems. Compared to those who underestimate themselves, self-confident people are happier, they have a more stable nervous system, rarely suffer from stomach ulcer or insomnia, there are fewer alcoholics and drug addicts among them, and they are more steadfast in bearing failure (Brockner & Hulton, 1978; Brown, 1991; Tafarodi & Vu, 1997). It is also important that, as we overcome difficulties and acquire skills, our success "raises" a more optimistic mind and greater self-confidence.
