I think there is an element you're missing there with your examples in particular. Once you create something for someone else, whether it's contributing to a collaborative effort or its a product for a customer, it no longer belongs to you. It belongs to the group you are a part of or the customer who bought your product. They are free to take what you have given them and do with it what they see fit, whether you like their actions or not. It's important to be passionate about your work, but it's also equally important to exercise detachment as well.

Unless you're truly independent, where your work for the most part only affects you, you are always working for others, whether you work in retail or manufacturing or research or medicine or what have you. Your efforts and your work is about more than you. With that in mind, whether you do or do not enjoy the work you do, it's important to do it well, no matter what the job is, because you're giving others a part of who you are, and it's important to give people your best.
