Anyone in retail sales/retail sales management?

How do you drive sales in retail sales management?

What do you sell?

What are some of the most important duties as a sales manager and how to overcome your biggest obstacles?

I'm up for a promotion and want to make my store incredible, i want to showcase my sales skills by coaching my team and driving sales as a team and no longer just individually. If anyone here is in retail sales management and could share some experience or advice I'd be grateful!
