When you are overwhelmed, it is OK to let go of one thing. And then two. And then three.
Of course, we all want to get everything done, and there are so many things that are important for us, for our dears, for our community, for our company. But you are not achieving more if you want to keep pushing when you are at your limit. You are just giving yourself, and everybody else, the illusion that things are progressing. So, cancel that meeting, skip the gym for the week, go for a take away instead of home cooking, spend half an hour longer in bed in the morning.
And there are only two things you can do about it.
First, build a solid ground. That would be knowing yourself, your situation, your story, your purpose, your triggers, your strength. A solid ground is what will allow you to not take change personally.
Second, open your arms. That would be listening to others, embracing their fears, helping them with their agendas, navigating the situation together with them, establishing long-term relationships. Open arms is what will allow you to make your solid ground even more solid.
One thing you should never do about change, and that would be trying to control it.
