the video - Day 13 (Business Class)

The video was kinda complicated because i wasn't sure what he was really talking about. I understood that he was talking about the logics behind a business and he was pretty much telling us the key point behind each business and also e was saying how they work. So I can't really say that I learned a lot of new things but the video itself was pretty interesting to watch and I enjoyed it a lot but again it was complicated to catch up everything, i think that i'll have to watch it again.
