You’re in high demand by a wide array of people. They all want to spend some time with you, and it could be difficult to figure out who to say yes to and who to put off until later. Prioritize the friendly folks first. The people who have always been flexible with you in the past now deserve top billing. As for the people who are too demanding and act like they’re doing you a favor by inviting you somewhere? Tell them to try you again next time.
