I give this advice to everyone. The first step it to visualize how you would be confident and fake it till you make it. I make no promises that everyone will be perfectly approachable but keep trying and I promise it will get so easy it will be natural.

My advice is to visualize the way you want to be around people and then fake it till you make it. I found it helpful and I hope you do :)
