Recently, I heard a great example describing a point of view which summarizes an entire outlook on life. The topic in which the analogy was used was a lesson on finding and keeping an attitude of gratitude.
Close your eyes and imagine a bush in full flower. Roses or something extremely pretty and sweetly fragrant. Look closely at the stems and see the thorns, sharp and painful.
How do you think of that plant? Is it a flowering bush with thorns, or a thorn bush with beautiful flowers? Do you see the bad in a good situation or the beauty in a broken world? Do the thorns drag your spirit down to anger and disappointment or do the blooming colors and pleasing smells uplift your spirit and give you hope?
Now, can you consciously change your attitude about it?
