Awesome in theory but much harder to achieve in everyday life.
This practice is meant to simplify the process in a practical way to a help turn your focus to your breath when you need it.
If it feels supportive, you could use a timer. Start small. Five minutes is great but you could even try one if this feels easier. If you choose to forgo using a timer, follow your breath for as long as your attention allows. This works as well because this practice can be done anytime and anywhere. When you are ready, all you have to do is focus on the rise and fall of your chest as you breathe in your natural rhythm.
As you inhale and your chest expands say quietly to yourself:
Notice the airy feeling of expansion this offers you. Think lightness and stretching outward.
Then, as you exhale, notice the contraction of your lungs as you become grounded into the center of your body. Say quietly to yourself:
Follow your breath in and out for as long as you are able while keeping the words 'sky' and 'earth' attached to your inhalations and exhalations.
Remind yourself often, mindfulness is a practice. You aren't meant to be perfect at it.
All you are meant to do is show up for the love within you in any way that feels most supportive to you.
Breathe into the horizon and let the sky envelop you in possibility.
Breathe down into the earth and root yourself in the wisdom and compassion waiting to be uncovered there.
