 B, where your feet are. It's so simple yet increasingly difficult in our modern world, and it is the first step to reducing stress in your life. This is becoming increasingly more challenging, giving the constant bombardment of distractions we face nearly every moment of every day. If I had to pick one fundamental strategy to help manage stress, it's to live in the present moment. Even if the present moment is stressful, A, you'll be able to handle it better when you focus on it, and B, there's only so much stress one present moment can offer. Stop getting upset over events from your past and getting anxious about a future that hasn't happened yet and may not happen at all. That's time travel, and it actually increases stress. Stay where you can have an impact, right here, right now.
