Best sales opener

Hello, guys!

So, as I am working in sales, I am constantly looking for ways to better myself and learn from others.

I know there is no such thing as "magic" or "perfect formula", but write in a comment below how do you approach customers, whether on the phone or in person, and what is the "opener" which works/worked better for you?

Much success to all of you,
Stefan

Ps - this is not much of a blog post, but I think of steemit more as a community, so it would be really cool to share knowledge, take advice from one another and help each other better ourselves.
