Try watching a child backstroking in swim class focused on extending her strokes further back and pulling her chin up higher and not start lifting your chin.
Try observing an employee excited about her job, willingly taking what comes her way and always seeking the next challenge and not feel energized.
Try mentoring an employee facing a challenge who you know can overcome it and soar if he would just believe in himself and not give up hope.
Keep your chin up. Take the good with the bad. And never stop trying.
