Salespeople: Get face-to-face rejections. Need to speak in public. Must dress well. Need to be confident.
Copywriters: Sit at home and type on the computer. Don't need to interact with people. Don't need to dress well. Can be shy.
I'm not here to say one way is right and the other wrong. But I am here to point out one fact:
BOTH salespeople AND copywriters NEED confidence. While your prospect can't use your body language as an indicator, many nuances in how you write copy can influence how you come off in terms of confidence.
If you're not confident in your copy or in your offer, why would your prospect be?
*This discussion is about confidence in copywriting, not about whether copywriters are cowards. That was just a headline to pull you in, baby.
