Technical people struggle in sales most likely because technical training is not sales training. Sales is a learned and highly skilled occupation.

Read a good book on sales, like one by Zig Ziglar. Effective sales is not at all about lying to customers. The best sales professionals rely on repeat sales, and you don't get repeat sales by lying to your customers.

I have a technical degree, and it includes zero sales training. Even born salesmen need practice and training.

BTW, when Boeing sells airplanes it sends out its top engineers. Engineers with sales training make darn good salesmen for highly technical products, and there's no way in hail you're going to sell an airplane to an airline by lying to them.
