Beware party crashers. Today, it may seem like your friends, community members, or social networks are raining on your parade. It’s never fun when others’ agendas worm their way into your pleasure pursuits. But it can also alert you that your boundaries need a boost. So seal off your painting corner, silence your notifications, or find other ways to prioritize your enjoyment. And remember: You can feel frustrated without picking a fight. Channeling that angst creatively will cool you down.
