When you’re unsure of yourself or you’re in an unfamiliar environment, it can often help to act as if you know what you’re doing and that you’re confident.  Many of us get flustered and frightened when going into give in-person training in an unfamiliar country or going to our first board meeting where we have to present.  By acting as if we are confident and taking on the stance of a confident person, we give ourselves the opportunity to feel what it is like to be confident, which in turn, tends to raise confidence.  Once you’ve acted the part long enough, you’re likely to naturally be confident.
