请各位帮忙把这段话翻译成英文吧,谢谢了!《当幸福来敲们》是一部很感人的影片，主要讲了克里斯•加德纳事业不顺，生活潦倒，妻子也因不忍穷苦的生活，独自去了纽约，但是克里斯•加德纳一直很乐观，并且教育儿子，不要灰心。功夫不负有心人，他最终凭借自己的努力，创办了自己的公司。这部影片让我明白了，我们做事要坚持不懈，遇到困难要积极面对，不能逃避，只有努力和坚持才能成功。

话在哪里

"When they knock on Happiness"is a very moving film,mainly about the cause of Chris Gardner • ring true,living down and out,and the wife's life because of the poor can not bear alone to New York,but Chris • Gardner Satisfaction has been very positive,and teaching his son,do not lose heart.Hard work pays off,he eventually on its own efforts,set up his own company.
