Thank you really to you all for your answers for the time you took for writing.

Knowledge and experience. But it usually comes after the time you needed it the most;))

"The wisdom is not wrinkles, it's gyrus....." I met a lot of people in my life and will meet more (if I live I hope)))) and among them were such wise young persons as old wise ones. Yes, I agree that the older the wiser or if youth knew and age could and bla bla bla.....everyone of us has wisdom (someone more, someone less) even child, but unfortunately not everybody use it and want to use and "develop"....<img title="Wink" src="http://www.italki.com/Scripts/tinymce/jscripts/tiny_mce/plugins/emotions/img/smiley-wink.gif" alt="Wink" border="0" />

This question let me think for a few days.  I shared everyone thoughts. let me know that I need to do something to get more wisdom.  Until this day, I do not  know what to answer. Thanks you for your all answer.

A  wise person should have fear of God; Wisdom is learn from past and try to not repeat again same errors.
Usually this happens try to living our life without any masks
