• Protect your time.
• Say no to somethings.
• Don’t live in reaction.
• Fight off the distractions in the environment. 
• Block access.
• Protect your brain.
• Guard it.

Remove all entry points to your brain except those you can control. Unrestrained consumption of media is mentally unsanitary. Engineer your environment, creating the opportunity for a self directed, purposeful world view.

In my experience Marcus Aurelius is correct, my thoughts color my world. Actually, without exaggeration. When I’m happy the whole world is happier. When I’m frustrated, everything contributes. Check this in your own experience. So it makes sense to work where we have control. If thoughts lead to feelings, and we see our feelings played out in the world, controlling or screening thoughts can help paint the world with happiness and equanimity. Not easy. Takes practice. Environment plays a huge role. Watch what notions you let in.
