It does not matter how fantastic your blog is, how much you pour your heart and soul into it, how genuine you are, because some people will still want to see you knocked down a peg or two.
In fact, the more successful you are, the more some people will want to see you fail.
You’ll probably receive some nasty comments from time to time from folks who want to make you look foolish and/or criticize you. That’s just life as a popular blogger.
Understand that your readers do not know you. Some will think they do and may even start to perceive you as a friend. This is cool as long as they don’t start hanging around outside your house, but ultimately, they do not truly know who you are. Therefore, any criticism that is aimed at you reveals nothing about you. It says plenty about the person that administers it, but that’s about as far as it goes.
To paraphrase Wayne Dyer, how people act towards you is their karma, how you react, that’s your karma.
You should deal with criticism the same way as you should deal with compliments, don’t take them too seriously.
If you take the compliments too seriously, you’ll not be able to deal with the hate comments when they arrive.
Whatever somebody says, simply thank them for their feedback. Then decide whether that feedback is useful and can help you move forward. If it can, great, use it. If it can’t, drop it because you don’t need it.
