I will not venture into speaking performance before a “paying” audience unless I am properly warmed up.
Athletes spend an hour or two getting warmed up before the game begins. Singers get themselves warmed up before a performance.
Every selling opportunity is a performance. Before you is an audience who is willing to exchange his hard-earned money for your offer.
If this is that one performance that will help you change the world, you must warm up, nay, steam up yourself.
