Are you stressed about an up and coming meeting? Well you do not need to be, just be prepared. If you have a important appointment or business meeting then you need to prepare ahead of time. If you need a laptop, some documents and other materials ready for the person you are meeting with, then make sure all of these are prepared before that person arrives.
This saves time and avoids the awkwardness of having the person wait for you to set everything up. Also if possible, arrive at the meeting location early so you can choose the right spot where you can setup and prepare for the meeting.
