Are these popular motivational quotes?

I am in college and am taking CPT-167: Intro to programming logic, and my instructor keeps saying that these quotes are popular but I am not so sure. I just want to know if any of you have heard of any of these before.

"Programming is challenging, the textbook is my friend, and the course content will save me a ton of time if I read it!"

"It is important to recognize and reference supportive resources, throughout the programming process."

"Programming consists of about 80% logic and planning, and 20% coding and troubleshooting."

"We create the best plan for our program solution and set out to code it! We also troubleshoot errors as we go, to keep us on track."
