A secret to staying present for longer periods

Here's a question that recently came up in a coaching session:

Client: I've been trying to be present and I've let go of a lot of thinking about the past… but now I'm constantly thinking about the future.

Me: If you want to gain any insight or clarity into deepening your level of presence, it has to start with presence. So, right now, are you fully present, with me, in this moment? Bring your full attention into the Now. Clear your mind. Take a deep, conscious breath.

Client: I can't. My mind jumps to what's next and issues with my work and family.

Me: That's okay, tune into your breath and your body. Do you notice any feelings in your body as your mind tries to run away?

Client: Yes, I feel really bad.
