Steve Pavlina: How to stop complaining

Perhaps the most important step in quitting the habit of complaining is to disconnect the undesirable behavior from your identity. A common mistake chronic complainers make is to self-identify with the negative thoughts running through their minds. Such a person might admit, “I know I’m responsible for my thoughts, but I don’t know how to stop myself from thinking negatively so often.” That seems like a step in the right direction, and to a certain degree it is, but it’s also a trap. It’s good to take responsibility for your thoughts, but you don’t want to identify with those thoughts to the point you end up blaming yourself and feeling even worse.
