Knowing what you don’t like is easy. It’s a bit lazy and also garners some “cool” attribute. Bring a hater or “Can’t be Bothered” type gives off a too cool for school vibe. But does it get you anywhere?
It takes effort to think through what you are for, what you like or what you love. You also have to be able to accept the criticisms that will come your way for supporting something others don’t, don’t like or demean.
To become successful and a decent person, you should focus on what you are for.
