• When adversity strikes, that’s when you have to be the most calm. Take a step back, stay strong, stay grounded and press on. — James Todd Smith [aka: LL Cool J] (1968-) American actor
• Keep your feet on the ground, but let your heart soar as high as it will. Refuse to be average or to surrender to the chill of your spiritual environment. — Sir Arthur Helps (1813–1875) English writer
    Note: The “spiritual environment” is often imagined as so ethereal as to not be practical in human affairs. On the contrary, it is the state of mind where we can find our most solid footing.

Comment: If you hit rock bottom, at least you now have a grounded place from which to continue.
