The question 0. to prepend to your list is: "How to dissociate between value of something to someone and the effort to implement it?". It appears that engineers are cursed of a chronic dismissive attitude toward things that weren't hard to make, because a lot of the most valuable things were hard to make.

This brings us to one helpful mindset is to get out of our own head, and consider the value of what we build from the perspective of the entities we build for. I say entities because I have this thing that I can delight a system whose input is the output of a differential amplifier I build with really low distortion, or a plant looking forward to being watered since the last time it has been.

So, after all that touchy feely stuff you probably know very well, as you have been building things that delight customers for a long time... Here are things you can do:

1. Get into more sales meetings if you can in order to witness and pick up from what people who consistently do it.

2. Offer technical help to your own salespeople and marketing people who are selling the very product you built. You have deep technical knowledge and you can be of real help for them to explain things. They will tell you about common objections or questions that prospects are throwing at them, and your input can be valuable. Why a specific bug fix or feature is important, etc.

3. Learn from your own salespeople and marketing people about how they're selling the product/features you built.
