@freemo Fear is one of the first things to conquer.
At the same time I'd add to preparing in the other departments of life so a person is not too extreme in their jumping into things or on people just to conquer talking to them (or mostly). Or do some overkill almost like a stunt which inversely kills the objective of reaching people more naturally or doing of things where it doesn't kill it yourself in the doing (others can hack things or can react with equally opposite in different spectrum and getting it the wrong way).
Even less people related perhaps needing thinking and yes lots of little tests... I guess I like the testing but with people communicating - but neither is perfect LOL
So there's more to it and sometimes not! And this is what people could help each other out with so it's not just pure unskilled or extreme courage.
but yeah generally start conquering fear (in your head) as the first thing to conquer, and the rest will follow...
