No, I did not study marketing. I learned a lot of about it and had a few marketing successes. You wrongly assume that only shitty products need marketing.
Also, I have a classic European upbringing. I was taught that if you agree with what others are saying stay quiet. Open your mouth only when you can point a problem and be straight in expressing your opinion. In the current world of political correctness, I am often perceived as having no socials skills. I know about it and try to adapt. But, especially when have not too much time, I am getting back into old habits. I have no intention to offend you or anyone else. Unfortunately, many have low tolerance for cultural differences.
