Recommended sales methodologies?

[Magnanimous]

I'll be getting into sales next year.

I'm thinking of using Jordan Belford's Straight Line Selling System. However I'd like recommendations from other people about which sales system I could use.

Go straight to studying Josh Lyons’ Actualized Selling. The most honest, authentic yet effective stage orange way you can possibly sell.

@Magnanimous Hubspot has good intro courses to help you understand the industry. That could help you. There are a lot of different approaches depending on the type of sales and your position.
