Vía Zen Habits, The Amazing Power of Being Present:

Practice, practice, and being present will become natural.
Here’s how to do it: whatever you’re doing, right now, learn to focus completely on doing that one thing. Pay attention: to every aspect of what you’re doing, to your body, to the sensations, to your thoughts.
You will notice your thoughts, if you’re paying attention, jump to other things. That’s OK — you are not trying to force all other thoughts from your mind. But by becoming aware of that jumping around in your thoughts, you have found the tool for gently bringing yourself back to your present task. Just notice the jumping thoughts, and lovingly come back.

Practice, repeatedly, in small easy beautiful steps. Each step is a wonder in itself, and each practice helps you to find that calm in the middle of the traffic of your life.

‘Drink your tea slowly and reverently, as if it is the axis
on which the world earth revolves – slowly, evenly, without
rushing toward the future. Live the actual moment.
Only this moment is life.’ ~Thich Nhat Hanh
