Only Step

One find that, if one is fortunate enough to be able to clearly and easily understand what one's greatest mistake of one's life is, then it could be said that said person is lucky that they are able to identify it as such, because that then suggests that the mistake could be fixed or rendered moot. However, if admitting a problem is the first step to solving it, it also remains, in the vast majority of cases, the only step ever taken.
