I now truly believe that you can not know if a trait is good or bad.

Based on your previous experiences, knowledge and views of the world you might view a trait as bad or good.

Look at the exact same trait 10 years for now and you might realize that now you view it as opposite.

For example the hustle mentality: you see someone who manages to work 12hours per day and be very productive and you might think WOW, that is a good trait, I want that. Then you might later realize that life is not all about working, and that having difference experiences and enjoying life might be a better trait.

Maybe the goodness or badness of a trait depends on context, and sometimes that hustle mentality is very useful, but other times is an impediment.
