It is better to have a bit of arrogance than to fall into self-doubt. Arrogance may not be perfect, but at least there is still confidence within. However, once overshadowed by self-doubt, everything one does or says feels hesitant and fearful. Many things, once said, are said; once done, are done. Being straightforward and decisive can actually save a lot of trouble. Confidence is crucial for a person; it can not only change the course of events, adjust the tone of emotions, but may even reshape the trajectory of fate.
