谁帮我理解I am a slow walker ,but I never walk backwards 的深层含义,最好写一段感触

虽然我走得不快,但我从不向后走
即
我是一种“滴水穿石”,“持之以恒”的人.
英语感触：
Consistent,effective effort leads to success.This is the moral of one of Aesop's fables,“ The Tortoise and the Hare.”
As the saying goes,slow but steady wins the race.The sprinter may run out of gas,but one who perseveres and never falters can accomplish great things.
There's still hope for the plodder.
