I have failed several times but I am not a failure.
Everything needs process. A process may be filled with not only joys and happiness but also tears and sorrows. People around you may not believe in you at first. However, you just need to keep going and working at your best. Listening to what people talk or following their standards will merely make you tired.
Wake up! The sun still shines! The sun still smiles! This is your life and you are the one who lives your life, so just keep on your move!
