Personally, I get a bit of a rush when working under pressure – I like the responsibility and the feeling of impending doom if a deadline isn’t met (perhaps because I know it will always work out in the end. At least, it has always worked out…).
If you’re working under stress, it can reflect poorly on your work. When working in fast paced and intense environments, I tend to beat myself up on oversights because they are completely avoidable if you just chill out. So breath, take a moment, stay calm, and deliver. Everything will be okay.
There are lessons to be learned from the Good and especially the Bad, and you can scream when the work is all over!
