Get used to it in private
Then get used to it in private with some friends/family around
In fact try talking to them and then talking to the camera
Then take them outside, with strangers around
Then just go out by yourself with strangers around
Ok jk op I haven't done the last outside steps neither, and I've only done voice recording which was still surprisingly hard to get comfortable with. Should be the same concept tho baby steps and then getting used to it.
