Tenderness and sincerity are in place when intention prospers. Intention can be developed by self-confident person only. Self-confidence grows from criticism – ability to split pros and cons of any specific object or idea. Such criticism arises when one is curious enough to study any object that is available or idea that is feasible or seams that way. Such objects are any simple or complex gadgets, everyday accessories and so on. Ideas – anything that includes activity and helps to develop self-expression.
Concerning the latter there’s one simple idea on the top: a person can be brought up when surrounded with different items of various complexities and in conditions of adequate access allowed to study them. Moreover individual must not be restrained with formalities or others’ harsh reflections that push towards some specific conclusions made on emotional level.
Of course, tenderness and sincerity are not the only major characteristics. And they need to be accompanied by much more intense and hard traits that perform defence and provide movement momentum. But these two traits are most commonly left behind or even wept out during personal development – whether under brutal circumstances and/or in case of psychological wounds left from childhood. And with lack of these warm details individual can never feel life outside of his own sphere: one is not a person that can feel his own boundaries and then step out of them.
