One possible version:

                            No Pains, No Gains

      It is obvious to everybody that the only way to achieve one's goal is

to work hard. Just as the old saying goes "no mill,  no meal". Have you

ever seen a man who succeeds just by idling about? Of course, the

answer is "No". So we know if you want to gain something, you will

have pains.

     The farmers harvest by a year of arduous work; the scientists gain

achievements by years of devoted researches; students get good marks by

working hard; even the little ants have their food by working hard day

and night. I know there are always some people who wait for the

opportunities falling on them. They may attribute their failures to lack of

good chances. Therefore,, there are so many people gaining nothing at

last. Clever men know that the more effort they make, the bigger chance

they will have to be successful.

      So, when others achieve their aspirations and you still gain nothing,

don't complain about the unfair fate and don't give up, either.

Remember: no pains, no gains.
