I'm not one of those people who believes we should run away from negativity all the time. I believe in the balance of yin and yang, positive and negative.
In starting my new 40-day meditation the other day, however, I was guided to go on a negativity diet for the next month. This means, not reading the news (unless it's really important) and staying away from negative people and situations as much as possible.
So what do I do? Within the first few days, I find myself engaging in a ridiculous conversation at a website over an email issue.
