Just spent some time reading this interview with Warren Buffett, and I remembered some of the best financial advice in the world is available in his newsletters for free:
Berkshire Hathaway Annual Shareholder Letters

My favorites from the post:

“Success is getting what you want, happiness is wanting what you get.” I won the ovarian lottery the day I was born and so did all of you. We’re all successful, intelligent, educated. To focus on what you don’t have is a terrible mistake.

Why do I come in at 7 every morning, can’t wait to get to work? because I get to paint my own painting and I like applause.

If I had been born earlier, I would’ve been some animal’s lunch. I can’t run, I can’t climb. I’d be talking about allocating capital and the animal would think, “Those are the kind that taste the best.””

Almost always good things come from good behavior. Don’t keep score in life.

After a talk at Harvard, I told them to work for who they admired the most, so they all become self-employed.
