do you think that taking selfies can build ones self-confidence?Actually it depends.selfie has no wrong per se and neither do the people,in some ways it can help to build and enhance confidence.but excessive selfie the same time taken on purpose to show something off ,it counters.Confidence is more from inner world not only outward,the unconfident people usually lack of objective or positive evaluation expected from others,so what they are supposed to do is to progressively improve themselves in abilites and then get validation and trust from others not only taking selfies.
Furthermore,try to be the kind of people of strong willpower who constantly surpass themselves and bravely face things they were afraid of before step by step.Sequently,confidence will come from deep inside and outward finally without amounts of selfies!
