Why I don't give investment advice

I fully agree with the idea of the text. Also, I like the idea that investment advice only helps few open minds. Usually, people just want to stay in existing thought patterns.

I'd add one thought: There are many semi-professional investors that work long hours to create the perfect portfolio. However, most don't even beat the market. One advantage of maximum diversification is that people don't have to make decisions for months. They can spend this time working one other things or just enjoy life.
