God this is so true. I teach compuster science, and I always make a point in one lecture to show the students how many tabs full of basic questions I have to open when grading their assignments. Nobody can memorize all of this, and it's so important to shake off that feeling of not being good enough just because you have to look something up.
Career software developer - Years and years ago I stopped reading programming manuals and trying to remember the syntax of languages. I just google the same basic things over and over, and often paste & edit example code.
