All I knew (as a kid) was I wanted to make the best out of my life and be a person of value to the society, and that meant doing my best and achieving my highest potential.

我所知道(作为一个小孩)的就是尽我最大的努力成为一个对社会有价值的人，这就意味着我已经做到最好，挖掘了我的最高潜力。

All I knew since a kid was that anyone with a broken neck would be disabled for life so my immediate question was would I ever be able to play football again?

据我所知很多孩子在脖子受伤后都改变了后面的一生，因此我立即问医生‘我还能继续踢球吗？’
