Limerick in fitness industry

There used to be many opportunities, but now there are fewer; Opportunities are getting less and less, so cherish them. If we don't run, we won't seize any chance.

People who used to like are now old; But runners are still so young, and I want to run and pursue youth.

I have forgotten all the promises I made before; Probably not worth forgetting naturally. In the future, just stick to the promise of running.

Previous ideals have been drowned by reality; It may be that the ideal is too grand and divorced from reality, and I will run and exercise in the future;

Most of the books I read before are out of date; This is not surprising, because things change and knowledge explodes, running and fitness need to read more new books;

I used to write poems, but now I blush; Congratulations, that's because your ideological level is much higher than before, otherwise you will blush when you are refreshed after running;

I fell down before, and now my scars are all good; That shows that you have matured after a long test, and it is good to run without stumbling after learning the lesson;

The tears that once flowed can't be squeezed out now; That's because you have stood the test and become stronger, and you will not be afraid of the cold wind after running;

The road I walked before, I can't go back now; The higher the road of life, the higher the realm of running in the future;

What's left of middle-aged Werther is to defend himself,

Cherish life and exercise. Whether young or old, running will become healthier and happier.

The industry is relatively successful.
