How do I stay calm when I feel like I hold it all together?

You say you keep the whole thing from falling apart. The schedule, the team's mood, the client's worry, the outcome nobody controls — you feel it all lands on you. That feeling is common. It is also false. Here is the honest version: you own your part. Your decisions, your effort, your response in the room. You do not own other people's fear, the market, the delay, or how the story ends. When you treat all of it as yours to hold, you are not being responsible. You are refusing to set down what was never in your hands. This is not about caring less. It is about carrying only what is actually yours, so you have the strength to carry that well.
