"لتكن محادثتك مع رجال الأعمال قصيرة وشاملة."

Simplified Meaning:

When you're talking to people who work in business, keep your conversations quick and to the point. Imagine you’re at a busy coffee shop and it's too packed to sit down and chat. You wouldn't want to stand in the middle of the shop having a long conversation, right? Instead, you'd quickly tell your friend what you need to say and then move aside to let others through. This helps your friend understand you fast and avoids wasting anyone’s time. For instance, if you were discussing a project with a co-worker, be clear and direct about what needs to be done and who is responsible. This way, everyone can get back to work faster and avoid confusion. In short, being brief and clear helps people in business stay focused and more productive. It also shows respect for their time, which they will appreciate. This approach can make you more effective and respected in the workplace.
