Hayley教口語，“言之過早”用英語怎么說？

said when you think it is too soon to make a judgment about the likely result of something because a lot might still happen or change

當你認為對某事可能的結(jié)果做出判斷還為時過早，因為很多事情仍有可能發(fā)生改變時，常會使用這個說法;言之過早、為時尚早、來日方長

Our progress has been fairly slow so far, but it's early days.

到目前為止我們的進度很緩慢，但來日方長。

I'm not sure if our book will be a success, it's early days yet.

我們這本書是否受歡迎，我沒有把握&現(xiàn)在言之過早。
