    When we think of leadership, we often think of strength and power. But what are these really, and how do they operate?

    Leadership today is not about forcing others to do things. If this is even possible, it is short-term. If you order someone to do something against their will, they may do it because they feel they must, but the anger they feel will do more harm in the long-term. They will also experience fear.

    Fear causes the thinking brain to shut down, making the person unable to function at his or her best. If they connect you with this emotion of fear, they will become less functional around you, and you will have succeeded in not only shooting yourself in the foot, but possibly making a very good employee or partner unable to perform effectively. Fear has no place in leadership.

    The way we affect people in a lasting way is by our own character, and our understanding and use of emotion. We can order someone to do something, which may be part of the work day, or we can employ them at the emotional level, so they become fully devoted to the projects and provide some of their own motivation (积极性). Today's work place is all about relationships.

    Anyone works harder in a positive environment in which they're recognized and valued as a human being as well as a worker. Everyone produces just a bit more for someone they like Leaders understand the way things work. They know money is not the only most motivating factor in the work life of most people.

    The true strength of leadership is an inner strength that comes from the confidence of Emotional Intelligence—knowing your own emotions, and how to deal with them and those of others. Developing your emotional intelligence is the best thing you can do if you want to develop your relationships with people around you, which is the key to the leadership skills.

合欢,合欢

李晓东

    很多年以后,我才知道,那是合欢。

    我九岁那年七月,母亲去小城开会,顺便带上了我,这是我第一次出远门。我们住在一个一眼看不到头的大院子,当母亲推开浅绿色的木窗,我来到窗前,一棵大树正对着窗口,那是我从来没有见过的一种树,从来没有见过的一种花,粉柔柔的,像一把把小小的扇子密密缀满枝头。树冠在十几米高处平平地铺开,将七月骄阳隔在树外,树下形成天然绿荫。

    我雀跃而出,跑到屋后,眼见得十来棵一般高、一般模样的大树肩并肩默立,每一棵树叶间缀满了粉红色的、棉絮一样的绒花,远远望去,形成雾状的效果。从那红雾里,飘出丝丝缕缕清甜的香味,我站在树下,看见那香正倾泻而下,从我的头顶,发梢,直到我的肩膀,我的手,我的脚下,那香蓬勃而起,又从我的脚下蒸腾,沿着我的手,我的肩膀,我的发梢,直到我的头顶,翻翻覆覆,重重叠叠,我在那香里,悄悄的,不敢发出一点声音。但母亲唤着我走过来了,她刚刚洗过的头发还没有干透,她的脸颊,不知道是因为洗过澡的缘故,还是被那笼罩在头顶的粉色映照的缘故,像胭脂一样。她从那香里走过来了,她唤我的声音也是香的呢,软的呢。

    又五年,我读到了史铁生的《合欢树》,这树的名字让我喜欢,于是就想从史铁生的笔下看看合欢的样子,但是文章始终没有描摹过合欢的样子。“与其在街上瞎逛,我想不如就去看看那棵树吧。”可是,史铁生终究没有走进那棵树。“我摇着车在街上慢慢走,不急着回家。人有时候只想独自静静的呆一会。悲伤也成享受。”史铁生的悲伤我那时并不理解,我所失望的只是,题目叫《合欢树》,可是哪里有合欢呢?

    合欢的名与树终于成为一体,是在羊城,我十九岁。还是七月,走进烈士陵园时,我大汗淋漓,奄奄一息,我觉得我马上就要死掉了。顾不得旁人诧异的目光,我把头伸向陵园一角的水龙头,其实那水也是温热的,我把水开到最大,长发在水中奔跑。立起身,甩甩头,感觉可以喘气了,头顶,却是一颗大树,那花粉柔柔的,像一把把小小的扇子密密缀满枝头,蓦然间,十年前的那树回来了。树干上挂着小牌子:“合欢,又名……”合欢,合欢,原来,史铁生笔下那棵始终未曾露面的合欢,早在我九岁的时候,就已经遇到了。

    那是一次仓促的旅行,仓促到不知道为什么旅行,仓促到不知道下一站在哪里。茫然地站在羊城街头,看衣着光鲜,满嘴鸟语的人流开开合合,我知道,这里不是我的世界。即使在这里邂逅合欢,与十年前小城的合欢相比,这合欢是傲慢的。虽然树是一样的树,花是一样的花,但是,那香里已然有着本土的居高临下、不屑一顾。

    又是七月,我已是母亲当年的年纪,依然在小城,依然有合欢,然而母亲再也站不起来了,她整日躺在病床上,医院的颜色,除了白,还是白。但是窗外是有颜色的,是有花树的,那花粉柔柔的,像一把把小小的扇子密密缀满枝头。我站在窗前,窗外是合欢,床上是母亲。

    但母亲唤着我走过来了,她刚刚洗过的头发还没有干透,她的脸颊,不知道是因为洗过澡的缘故,还是被那笼罩在头顶的粉色映照的缘故,像胭脂一样。她从那香里走过来了,她唤我的声音也是香的呢,软的呢。惊回首,病床上的母亲静悄悄的,一点声音也没有。

    我知道了,史铁生为什么终究没有走进合欢。
