I wouldn't say it's impossible. There are a few ways to fight this feeling. First, try and understand why you care so much, if that excess of care is giving you too much pressure. Maybe you care too much because that's your livelihood, and that prevents you from taking risks? In that case, try and shop for other jobs and maybe seeing what other options are available will make you be more relax. Or maybe you care too much because the timing means you have only one shot at whatever you're working on? Then work beforehand on having more options. Or lowering the risk of your project failing. Think about a plan B, or C. What I'm trying to say basically is that if you feel that you're at your best when you don't care too much, find ways to create that distance or relaxation. That might need some time, logistics, or introspection, but it's certainly worth it.
