2. Have a negative attitude toward everything. People who pretend to think that you can simply willfully infuse yourself with positivity annoy me. Negativity is how individuals react to certain environments. You can change some features in the environment and fix that, but simply demanding everyone to be positive is stupid. It's essentially a demand for suffering in silence.
Yep, most people most of the time get those as a reaction to their environment, but they are not caused by the environment, positivity and negativity are always self inflicted.
Anyway, I don't think a positive attitude is always the best for a person, but most of the times, it is.
