One possible version:

Success will be gained after times of failures as long as we are good at drawing lessons from failures or mistakes and stick to what we are doing. There is a message carried in the proverb "failure is the mother of success ."

I will take my experiences of learning as an example. When I began to learn English, I was so slow and clumsy that I read words wrongly from to time. My pronunciation made me laughed at by my classmates. But I didn't give up. I keep practising reading English aloud every day. And my teacher gave me a helping hand, getting me right whenever I made an error. Finally I even got a chance to take part in the English speaking competition and won the first prize.

In a word, as long as we don't lose heart and keep on trying. We are sure to go through failure and achieve our goals.
