One of the best lessons I've ever learned from my Mary Kay director was about space. It's totally unrelated to makeup, but absolutely perfect. Think of every person in your personal space. Then strip them of how you know them, how you're related, the history between you, etc, and think only about their presence in your space. Is it positive, negative, or neutral? Then make changed based off of your assessment. Get rid of the negative people (or limit time if you're related or work with them and can't just block them out). Then consider the neutral people. Why bring them around if they don't add anything? At that point, you can just be by yourself.
Why waste time with anyone less than a positive influence on your space?
For the first time in awhile, I actually took someone's advice and listened. Naturally, since I am in social media, my first inclination was to apply this to my Facebook and Twitter. I went HAM on the unfollow and unfriend button. If you are on my newsfeed sub tweeting your ex, calling out your "haters" or whining about politics, you became dead to me.
While some may think it's harsh, the effects of getting rid of people that bring negativity into my space has been amazing. Rather than getting sucked into drama, I am now filling my space and thoughts with positive and meaningful messages. Viewing my social networks became actually a release from stress and a way to refresh myself and keep tabs on people and messages worth looking at.
It's your social network. Fill it with people worth being surrounded by.
