長い英文ですが

英語が苦手な方は

ネット上の翻訳で訳してみてください。(でも、人のこと言えないかも(笑))

でも、要約すると

『the important thing is to keep getting up and trying again.』の一言につきると思います。
この場合のgetting upは起床というより

立ち上がるという意味だと思います。



There's often a very thin dividing line between success and failure.My daughter Holly reminded me how I sat her down when very young and told her I would likely have to take her out of school. We were struggling to make ends meet and my wife Joan offered to sell our old car to help.Fortunately we were able to make it through and Virgin has gone from strength to strength. But for every success story there are hundreds of near-misses.Every entrepreneur usually fails several times before succeeding, and the important thing is to keep getting up and trying again.By Richard Branson. Founder of Virgin Group
