For my 'career' it was an almost useless waste of time.
I actually did learn
a lot of solid engineering.
But that's one of life's greater disappointments:
Alma Mater teaches you how real, genuine, solid engineering has to be done to get high quality, reliably functioning results. That's what you wanna do. That's why you started to study at university in the first place. To do things better. To produce the best there is. To make the world a better place.
After U you get a job. You enter the world of business, and you learn: That's all genuine BULL-SHIT!
Nobody gives a damn fuck. Everybody is whining when zillions are shoveled into the crapper because the junk ain't working right, but nobody wants to listen to the least shit about how it has to be done to do it right.
Later you'll learn: Shoveling zillions into the crapper ain't a mistake. It's part of business strategies. And you could help them to burn even more money in even shorter time, because they don't have the expertise to do so, but you have, but they still won't listen to you.
So:
Looking back it doesn't matter, that I was too immature, drank too much beer, smoked too much weed, had too many parties, and too many women, and most of my time binge-played computer games, instead of studying 'right.'
The stuff I missed that way had been even more wasted effort for the garbage can.
So, I had the time of my life, one can only have when you are younger than 30, have no job, no mortage, no wife, no kids.
Just simply enjoy life!
The rest is a pipe dream anyway.
