In the length of time it takes your heart to beat, once, life as you know it, can change drastically. Jobs are lost, relationships end, accident and incidents occur.
Loved ones die.
Life altering events have an instantaneous impact on your perspective. Things and people you took for granted are suddenly precious and treasured. The delicate thread of life is revealed. When the things you have and the people you love are not enough to sustain a happy, hopeful and grateful attitude, your dreams and desires are living on a shaky foundation. You have nothing solid to build upon or fall back on.
