翻译：词都很简单，但是句子不懂

Question

I was such a fan that after reading that he walked at a rate of 120 steps per minute, I practiced his pace until it became second nature.

Answer 1

他是我的偶像。 读到他能够每分钟走120步后，我也(勤奋)练习，学他的快步伐。要直到它成为我的自然习惯

Answer 2

意译咯：
那时我可是他的这样一个“粉丝”：就是读得他每分钟走120步，我也练到了和他一样的步率，直到成为我改不了的“秉性”。（意思说我那时有多么地崇拜他）
