The days of university

Last time I moved house, I threw away the majority of my university notes. I'm going through what's remaining, right now, and tossing out all the ones that aren't to do with traffic and transportation, because I know I won't be going into other branches. So, wastewater & water, geotechnics, hydraulics are all going.

I just stopped to read some of it.

IT'S FULL OF EQUATIONS AND SYMBOLS AND WORDS I DO NOT UNDERSTAND ANYMORE.

Did I ever even learn that? It's an alien language!

Hydraulics is not so bad. Soil mechanics, though, is making me go O.o"""????????

Oh man. I feel so bad now. It's like all this information I've once learned has all gone to waste.
