Wow, so short and powerful is this statement.
It reminds me of this:
Wisdom gained from experience teaches you to learn from your own mistakes whereas the truest from of wisdom enables you to learn from other people’s mistakes.Me
I suspect Franklin adapted this quote from his own life experience and from one of the Greek philosophers.
Always remember, when you point your finger at another, you got three coming back at you.
As the Good Book says, first take the plank out of your own eyes SO then you can effectively removethe splinter from another’s. It doesn’t mean we shouldn’t help another but it does mean we need to attend to ourselves first so therefore we can help best. That also isn’t an excuse not to help or sit waiting on perfection before you act as perfection is often the enemy of good.
