When I was young and foolish I was very concerned about others opinions and didn't want to upset anyone. others used to say how I should live my life. And just I responded with some polite bs like "yeah you probably right" or "I will think about it" and later just did what I wanted to do. It was better than actually living my life acording to someone else's will but it still was not entirely my life. After some time I discovered the pleasure of saying "No. I will do things my way. If you like it thats great. If not you should get out of my way". It was one of the best moments in my life. Trying to please someone else at a cost of your own happines is the worst possible crime. the only person we must please is the one we see in the mirror everyday. Everybody else are lucky enough if we allow them to be part of our lives.
You are not selling slaves, drugs or guns so you are not doing anything wrong. Some miserable little shits will complain no matter what you do. They are a waste of time and energy. But as long as you are happy with what you do nothing else matters.
