To accomplish the goals of your life, you should always be very confident. However, it is not easy to be super confident. Whether you want to go on a date with your co-worker or do well in your job interview, without confidence every task can appear quite daunting and unachievable.
As confidence is an emotion, it can grow only when it is triggered. You can build your confidence only through the efforts you put towards building it. When you are super confident, you can face any difficulties of your life courageously and get motivated.
