Men's faults do seldom to themselves appear.
I know my flaws before other people point them out to me.
I have a pretty good idea of what I am not good at and have it front and centre of my consciousness every minute I am doing it.
When you notice a fault in your neighbour, search for the same in yourself.
I have met many entrepreneurs who have the passion and even the work ethic to succeed - but who are so obsessed with an idea that they don't see its obvious flaws. Think about that. If you can't even acknowledge your failures, how can you cut the rope and move on?
Not to alter one's faults is to be faulty indeed.
Every person is observant of the flaws of others and blind to his own flaws.
I have identified my weaknesses, and I am working on those.
The truly persuasive must step out of themselves and see their own flaws first and admit they could be wrong. Then, when they correct for that, you can be truly persuasive.
