I do not agree with the political points of those quotes.
There's nothing wrong with encouraging work to be successful, and people should work hard. However, sheer dumb luck (especially birth circumstances) plays a major role in whether or not someone will be successful in life. Work is important, but the quote's message is often used by the economic right to discredit programs intended to help the disadvantaged, and I don't agree with the notion that most poor are poor simply because they're lazy, or have some other character flaw. Though if the quote is just to teach people not to expect success without effort, I guess that's fine.
The second quote is fine, I didn't read it closely enough, sorry about that.
