Im sorry that time you asked me how to say about the sentence in English, I was studying Calculus and it was so difficult . The teacher who was teaching ,looked at me and then I couldn't type you back, Really sorry for that. I have got to tell you something.... its.. you need to face to face with all of situations which come and go... by yourself if you really need to go ahead to be better you shouldn't look back and feel bad when you fail... keep its up. You are going to be cool. Be yourself keep practicing, keep learning, keep talking, be confident !!!!!!! No matter what would be happen after we did wrong. No one cares!!!! Ok?.... let's do it what you want. I believe that one day you will be proud of yourself that you could do it well!!! Cheer up!! With all my love!! You can do it!!!! Be confident!!!
