Letting others define you will make you miserable. You should be genuinely happy. I doubt that half dozen people remember me from high school or college. I wasn’t cool at all. I bet every one of my trainees at work remember me, though. Now, I don’t worry about what other people think. I quit that when I had to give my first speech at work when I was 36. Now, we are the first ones on the dance floor even though I have no idea what I am doing.
I used to have the same attitude about romance novels, not cool. My article Stereotypes and Prejudices Everywhere explains how that changed! I have posted 27 reviews on Amazon for romance novels in the last 4 years.
I post whatever interests me at the time and don’t worry about it. I am surprised which posts are popular.
