could you please help me to understand the use of "a dash of" here?
A guy is trying to build an artistic career. His first small steps were successful, so he decides for a bigger one, and with lots of bravado and a dash of one-hundred-percent real confidence, he goes on to audition for the new play.
I think I understand the words :), yet I feel like something eludes from me in this sentence. I'd appreciate any explanations, comments on the nuances etc.
Thanks for any help :)
