Acting like divas.
Thinking 'oh, I'm published...I'm the greatest thing since sliced bread'.
Bad-mouthing others all over the internet.
Telling someone a confidence and two days later seeing your words splashed all over the internet.
Whatever happened to common courtesy?
Not naming names here, but I've learned a past acquaintance is up to his/her old tricks. I'm actually saddened by this; apparently the fact s/he's lost friends hasn't deterred this person from changing for the better. If you're going to bash others, be prepared for a backlash. Don't be stunned if someone has the nerve to criticize you back.
In fact, let's try something radical. If someone criticizes you or your work, by all means, go off in a corner and have a good cry. But instead of retaliation, laugh it off. Don't sink to their level. It only makes you look small and insecure.
And who wants to buy books from a selfish author? I'd rather buy from a friendly author, one who admits his or her mistakes, rather than being vindictive about past wrongs.
Think about it.
