I wish I could remember exactly what the "Elvis" is.
When I choose a song for a choreography I literally listen to it for hundreds of hours. Over and over. There have been days that I listen to a song for 8 hours straight on repeat while I work. I sometimes get so caught up in the details of its every little nuance, what movement should go where, how will this translate to the audience, etc. that I begin to hate it. I begin to think my song choice is all wrong. That the audience won't like it. They'll be bored with it. My costume isn't right. I might not do the song justice.
I over analyze. I second guess.
I forget that in reality, the audience will be hearing the song with fresh ears. Seeing me with fresh eyes. I forget that the only way I could ruin their experience is to not dance to the song at all.
