It is natural for a human to get influenced by those who impress him/her. Each of us is unique hence one must focus on identifying his/her own uniqueness rather than develop an inferiority complex.  Do not blindly try to be like them and compete with them. Be completely yourself, laugh at self and live a life suiting your sensibilities because what you have inside (the compassion, the gratitude, the delight & happiness at others achievement) is what matters.  Self confidence helps you face successfully an adverse situation beyond your control.
