      One of my fondest memories as a child is going by the river and sitting idly on the bank. There I would

enjoy the peace and quiet, watch the water rush downstream and listen to the chirps of birds and the rustling

of leaves in the trees. I would also watch the bamboo (竹子) trees bend under pressure from the wind and

watch them return gracefully to their upright or original position after the wind had died down.

     When I think about the bamboo tree's ability to bounce back or return to its original position, the word

resilience (恢复力) comes to mind. When used in reference to a person, this word means the ability to readily

recover from shock, depression or any other situation that stretches the limits of a person's emotions.

     Have you ever felt like you are about to snap (突然折断)? Have you ever felt like you are at your breaking

point? Thankfully, you have survived the experience to live to talk about it.   

     During the experience you probably felt a mix of emotions that threatened your health. You felt emotionally

drained, mentally exhausted and you most likely endured (忍耐) unpleasant physical symptoms (症状).   

     Life is a mixture of good times and bad times, happy moments and unhappy moments. The next time you

are experiencing one of those bad times or unhappy moments that take you close to your breaking point, bend,

but don't break. Try your best not to let the situation get the best of you.   

     If the going gets tough and you are at your breaking point, show resilience. Like the bamboo tree, bend, but

don't break!
