I guess I've worked long enough to be more pragmatic than that Jen. I actually do like design engineering type stuff. I can go to work and enjoy that so it isn't like it's a bad thing.
And like you said about history, the job opportunities for botany are more limited. A good engineer can always find some kind of interesting work!
So, probably I'll stick with that - since the classes I already have will apply to that. But, I will definitely take some botanical type classes just for my own enjoyment. If nothing else, it *hopefully* would be some classes I would enjoy enough to have easy A's in. Hopefully.
Minor in botany?
I don't think any learning is really a waste of time. So maybe you won't get a job with it. But maybe when you retire, you'll grow the world's best herb garden.
