阅读下面一段文字，根据要求作文。

某寺院有两棵树，一棵是高大挺拔的梧桐，一棵是干朽瘦弱的女贞。它们之间有一根粗黑的单杠，女贞树那端和梧桐树这端用螺丝和铁箍固定在树干上。平时，这儿虽游人如织，但很少有人注意。直到写有生命树的一块牌子挂在梧桐上，它才成为寺院的一道风景。原来，60年代，这个寺院曾被接管过，所有的房舍都被改做了囚室，专门关押那些被打倒的人。据说，在这儿被关押的人很少有活着出去的，因为这个地方的改造力度比其它地方都严厉。然而，有一个人，虽然在这儿蹲了十二年监狱，却站着出去了，这个人就是这个市的市长。他在非正式场合总是说，他能活到现在，全靠寺院里的那棵梧桐树。他被关押进寺院时，那棵梧桐树有茶杯那么粗，正对着囚室的窗口。有一天，看管他的人在这棵树与女贞树之间架了一根系沙袋用的单杠。起初铁箍是紧紧勒在梧桐树上的，第二年树长粗了就勒出一道沟，三年后一半的铁箍勒进了树里。已被囚禁了近四年且经常挨打和批斗的老市长正被折磨得万念俱灭。他看到这圈铁箍，心想明年这棵树的生命也许就要结束了。然而，就在第五年春天到来时，那棵梧桐树的生命不仅没有结束，而且还把那个铁箍完全吞了进去。后来，老市长回忆说，面对此情此景，我也能平静地对待囚禁中的生活了。

在人的一生中，有时会遇到一些令人难以忍受的事情，它们不是贫困，也不是疾病，而是外界强加给你的一种桎梏。请以“桎梏与生命”为话题，联系社会生活实际，写一篇文章。注意：1.立意自定。2.文体自选。3.题目自拟。4.不少于800字。

It might sound ridiculous that goal setting could actually hold you back from completing tasks and dreams you may have. But it seems like everyone tells you should be setting goals for everything you want to accomplish, short term and long term. Goals can help you sometimes, but in some cases they just lead to constant frustration and they actually bring you down.

Let’s look at this a little closer with an example. A lot of people might set forth as a goal. Many people jump online and are looking to start a business online as a way to make money from home and let’s say they set a goal to make $10,000 in their first month. They do this because they seem tons of people making large sums of money in very little time so they think, $10,000 a month, that shouldn’t be too hard.

But what happens when you only bring in $1,000 in your first 30 days online? If this is pure profit you might still be happy but this is nowhere near reaching the goal you originally set out to meet. So naturally you would feel like you failed to reach your goal and you may be a little disappointed in yourself.

If you continue not to reach this goal month in month , it starts to add up and really weighs on you. I’m not saying that they are bad and you shouldn’t set them but you need to realize that you should not be emotionally attached to your goals.

An alternative approach would be to set certain milestones for when you want to accomplish things and start out small. Build your confidence by accomplishing smaller feats and if you overproduce, then it will be a nice surprise. You have to have some sort of end result in mind but break it down in to a day by day task. It makes it a lot easier for you to handle by just knowing everyday you have to complete a few small tasks and over time the snowball will roll into great things.
