Someone said "Learning what you don't want to do is pretty valuable, it may be as valuable as figuring out what it is you do want to do." Opinion?

Well, statistically speaking even the most active among us will not do far more things than we will do. So finding out one thing we don't want to do is, on its own, less valuable than finding a thing we do want to.

However, sometimes there are things that seem appealing and/or we are told we should be doing. THOSE are the things it is really valuable to find out we don't want to do.
