Dance badly with full commitment. Half-hearted dancing is the only kind that looks awkward.

Half-commitment is the thing that actually looks awkward. A body that is partly dancing and partly apologizing for dancing reads as uncomfortable, while total commitment to something objectively terrible reads as fun, which is why people join in instead of watching. Hesitation is more visible than any mistake.

Take something you do half-heartedly out of self-consciousness and do all of it this week. Sing the whole chorus, dance the whole song. Notice how fast the attention moves off you and onto what you are doing.
