I think my biggest challenge as a student was my inability to remain on topic. I’d go to the library to work on a Limnology or Population Ecology assignment and leave at midnight with a comprehensive knowledge of Leave it to Beaver (yeah, I’m old - what are you going to do, eh?) or cantilever bridges or whatever. University libraries were pretty much an invitation to go down rabbit holes. I’m over 70 now and I’m pretty sure I’ve retained more of the extra-curricular stuff (only some of which was extremely weird) than my course material.
Okay, so I guess that was all off topic. Oh well.
What were we talking about?
