I had only two horrible teachers to be honest, so i consider myself lucky.
One was in both primary and middle high, the other was at my university.
First one basically stripped me of my ability to count big numbers in my head - i could multiply and divide 4-5 digit numbers easily. She just didn't believe it and marked everything as failure unless I've written down everything step by step.
Latter on she was my chemistry teacher - average grade for my class was just one mark above failure. When we got new teacher i could score top grades easily - not because she was more lenient at grading - but she actually could convey her knowledge.
At university we had a numeric methods teacher who didn't grade the method, but the result. a single mistake in writing things down resulted in a failure of whole assignment. We never did any theory, just did everything by hand. Thankfully numeric method teacher at my masters was way way better - he was actually teaching us.
It's funny how little organizational power structures change:
I only had two horrible bosses to be honest, so I consider myself lucky.
One was at my first job out of school, the other a few jobs later.
Fist one basically stripped me of my confidence in my coding ability - I could build complex algorithms easily. She just didn't understand minor complexities and made me use more, simple algos and over document.
Later on another project, we were always behind schedule, just one fire away from the project collapsing. When we got a new boss, we were able to complete features easily, not because there were less features, but she could actually convey requirements.
At my later job, the boss didn't care about code quality, just that PBI's were moving through. Single mistakes brought down the entire app. We never did root cause analysis, just patched symptoms. Thankfully a boss that came in later was way better, he actually pushed quality.
