I have no idea how to develop those skill.

I've been in some form of programming for 30 years. I know myself well enough to know I couldn't sell water in the Sahara desert. I just don't have it.

I can recognize good sales people, though. They are much less "true/false" in thinking than a good programmer. I didn't realize it for quite a while, but it's a symbiotic relationship-- programmers need sales, sales need programmers.

Good luck.
