Cooking on a line is very different than cooking for friends and family, though. Cooking for family and friends is less stressful in some ways because you're not cooking for customers under high pressure all night, every night. But you are also responsible for every part of the meal, not just your station, so coordinating everything can be a bit of a hassle, especially when it's a special occasion or when there are lots of mouths to feed. I have a lot of respect for line cooks and professional bakers. Not a job I'd want to do again.
I should also add that cooking for family and friends (real friends) is very low pressure. When the meal doesn't turn out perfectly or something goes awry, if the company is good, the food will be just the way they like it.
