This is a vital quality. Self-esteem grants happiness. It helps us believe in ourselves and our capability. A person who values themselves will stand their ground well and be able to defend what they care about. Self-esteem is fairly easy to cultivate: one need think of the quality. At first, it may seem high or low, but these two states lie on a scale.
As you analyse the feeling of either, they will balance each other and the presence of a strong, healthy opinion of yourself will grow clearer. You are realising ‘I value my own life and I wish to succeed.’
Think ‘self-esteem’ for two minutes per day and watch how you change.
