Saw a Ted talk that said the same thing. The guy over came some social anxiety by actively putting himself in an awkward situation each day (his was asking if he could get his coffee for free at the coffee shop). Once he got use to low stakes situations where people were surprised, confused or mildly judgemental (but also amused or just disinterested) it was easier to do things that actually mattered without worrying about people's reactions. And he got a few free coffees.
