Incoming BB sales analyst.. soliciting advice from literally anybody with any amount of tangible experience.

I'm about to start on my bank's emerging market sales desk. Any advice? What are some things you wish a senior person had been totally honest with you about? What advice would you give your past self? Any product-specific info would be hugely appreciated, but totally not necessary. Advice can range from stories of yours to emotional to practical etc. Literally, anything you guys can say about what I'm getting myself into is valuable to me. Thanks in advance.
