英语翻译

这句话完全是中文修辞,从英美人的角度讲,不可能翻译成完全一样的英文.比较接近英美人的习惯说法的翻译是：
I must act like man,with my courage I shall defy the cruel twist of fate and stride on to make the journey of my life no longer bumpy.Please let the fierce,merciless blaze burn my past and by so doing,I shall turn my history into ashes and turn over a new leaf.
其中：荆棘的命运：the cruel twist of fate
迈开脚步走下去:stride on
把...化为灰烬:turn sth into ashes
中心塑造自己:turn over a new leaf
希望这些 idioms
