Missions:
1. Call complete strangers and try and have a conversation, or tell them a random joke.
2. Make strong eye contact with everyone you walk by and then give them a smile and say hello.
3. Give random strangers on the street complements.
4. Stop complete strangers and tell them an extremely corny joke.
and remember to have a relaxing, but very confident voice. just by faking a confident voice it will make you feel much more confident.
Here's a video from my channel where we do this first mission:
