I think often of my Humanities professor. I was a Computer Science major and that paid off for me professionally in immediate and direct ways. But it's my humanities professor who taught me how to write.
She wanted the writing to be short, grammatically correct, and require deep thinking. She'd return the paper to you immediately if she caught even a single grammar or spelling mistake.
But the toughest part is that every time I put my thesis in front of her she'd say back to me, "Ok, if that's true then what does it imply? Take the next step."
Every time she said that I'd be wracked with doubt thinking that couldn't think any further than I had already thought.
So, sure, now I work at a writing company. But even if I didn't work here, I would credit her with helping me build a muscle to think deeper and sharper and then communicate about it. Over time, that one Humanities class equaled the value of my entire Computer Science degree. It's how I got into technical leadership and then management, and then entrepreneurship and then, in large part, how I got this job. Thank you Professor Monessa Cummins.
