Efforts = Gain ?

There's a saying, from long long time ago....

"... for every effort that you pour onto the things that you are working on, you will always regain back everything that you have poured out"...

Mean for every ONE effort you took out, you will get back ONE gain....

It's also written in Chinese in this way, "Yi Fen Geng Yun, Yi Fen Shou Huo" (sorry because i don't have any chinese input software in this computer...)....

Since young, when we're still in primary school, teachers used to tell us that quotes as they will say that we must put in every single effort in everything we work on, then only we will be able to achieve good results in the end.... Do you believe that it works....?? At that particular time, i do believe because i'm a good students... =p

But as time goes by, i realized one thing.... If we always look at that way, we will only keep thinking and counting to get back everything that i have taken out before this...

For example, i had given out 80% of efforts, i must get back 80% of gain....
* 80% out = must gain back 80% ....

If it's like this, aren't you just keep minding about every move u moved,right....? You will never be satisfied and happy in your life although you achieved results, because you will only KEPT counting how much i can get back, but never think of how much i can actually sacrifice for it and don't ask for reply.....

I'm not saying that you can simply sacrifice for anything, but after this, if you can do things, take it easy but do it seriously, and not always counting the gain, you can actually do it even more happy and relax.... Think about it...!!!
