> I can usually come up with working code to do whatever I've ever wanted to do

Been working as a programmer for 25 years, and I’ve never read (or considered reading, or felt the need to read) a book on data structures or algorithms.

Also, I’ve seen plenty of people who are employed as programmers who simply cannot come up with working code. I don’t see how you can write working code without problem-solving skills, as by definition you’re solving a problem by writing working code..?

(I don’t really have a point, sorry, this just resonated with me)
