Acting bold and confident is especially potent when you are creating a first impression,
as these have the most impact on others, a bold confident first impression can do wonders
for how others perceive you in future encounters. You gain respect immediately, people really do make up their minds about a person by what they see and hear when they first meet someone, and so if you can come across as confident, (even if it is only acting)
people will believe you are as they first perceived you, and will in fact look for ways to
re-enforce their judgment in future encounters. Remember that hiding yourself form the
world and playing down your abilities and strengths benefits no one in the end.
