The creative process is an interesting one. Collaboration is always key, and teamwork is what makes it happen. No one actually owns any of it. It's free-form reality. It's linear and it evolves and it really only owns itself. There's also no such thing as an "original idea". Originality doesn't lie in an idea. There are no original ideas. Originality lies in the INTERPRETATION of an idea. Any jackass knows that. Or at least they should. If you don't (talking to you, shitty teammate), then you should step aside and leave more room for all the other crazy cooks we got in our kitchen.
That said: When you work on a part of something and then pass it on to someone else, the thing that you worked on isn't yours anymore. But in the creation process you left a trace of yourself in whatever you touched. So if the next person now works on the part containing a trace of you, they owe you enough consideration and respect to at least involve you in the discussion before they completely reinvent and throw away the piece of the puzzle that contained a trace of you. Am I right??? Or am I right??
You can rest assured that I will not be stepping in the way of karma when it comes around next.
