The useful and highly strategic approach to lectures/class in university. By going to class you must take 50 mns worth of notes as opposed to later copying said notes in let's say 10 minutes. 50-10=40. Hennings rule of 40
You going to that shitty law lecture Sam?? Nah, ill just use Hennings Rule of 40
