When you are capable enough to do something but you are not trying to do it that's your biggest failure ,try to come out from your comfort zone and do it you will definitely get success. And always stay smiling !!
Life is too short to be a sad and negative, try to find a happiness within you which makes a positive path to live life. Live life like a child without worrying about the things and people who don't add a value in your life. So, stay happy and keep muskurana.
