Advice- I want to do sales proud. Mentorship needed

Hi! So a little background I (34F) work on the supplier side of a small but up and coming wine brand where I manage my states sales. In my role I need to build leads, research opportunities for growth, manage partnership with distributer and sales force, maintain relationships with key accounts, cold calling, and of course close all the deals in order to make my year end quota.

This is my first real sales job as I worked in restaurants for a long time before this and I’m making big girl $ for the first time in my life. I really want to do well on this side of the industry, I love the brand I work for and want to help continue building them up (plus the bonus is pretty nice if I hit my quota) but I find myself struggling. I constantly feel like I’m not doing a good enough job. I struggle with feeling confident closing deals, feeling like people think I’m not doing a good job/deserve this position, and managing all the nuances of this job.

I’m hoping to get some tips and tricks on how to feel confident when face to face cold calling and how to actually close the deal. I’m usually pretty good about small talk and building rapport but when it comes down to the handshake I have a hard time pushing for the commitment. Sometimes I feel that I am too passive/nervous or “feel bad” for asking for the sale.

Should I have an elevator pitch? I cringe at myself when I come off as too “sales-y” .Are there any good books or YouTube videos for perfecting the sales mentality? Also how to manage time effectively when you have no one watching? I really want to excel in this role and continue to push my career forward.

TIA!

TLDR how do I let go of the “I want everyone to like me” mentality and be a confident, respected boss babe who can close any deal?
