勇敢地去尝试新事物，即使一开始做得不好。

I always tell my kids, 'If you're going to do something, do it well. And if you're not going to do it well, don't do it at all.'

【释义】弹弓打鸟，千金不如泥丸合适。【延伸】一件事有很多种解决办法，找到最合适的一种，才能在每件事上都事半功倍。最贵的，不一定是最合适的，最合适的一定是最好的。

The more you dwell in the past, the less you prepare for the future.
