Do you know why meditation is so effective?
The lack of thinking.
Thinking is something that takes energy. It also has a chemical effect on your brain that can drastically alter your mood. Thinking, 24/7, is the best way to stress yourself endlessly.
Stop. Take a deep breath. Open your eyes and look. Don't think about what you're seeing, don't think about what you hear, what you smell, just. Experience it. Breathe in, and out. Listen to the sounds around you.
When speaking with someone, listen to everything they have to say, fully, and /let them finish/ before thinking of a response. You won't interrupt them this way, your thoughts won't get in the way of you understanding them, either.
