Proper diversification means investing in uncorrelated assets, and investing in multiple assets needs multiple sets of knowledge, more hours of research, and more marketfollowing. It is definitely more work for an investor.

Everybody does some sort of diversification. It is the extent and broadness that varies according to risk tolerance.

Market price matters at only two points in time. When you buy and when you sell. In between, it is only a distraction.

When analyzing a business, keep things simple.

Market quotes change every second, but business evolves steadily. You have ample time to evaluate a business to buy or not to buy. There is no rush.

Nothing wrong with buying high PE stocks; however, expected business growth must justify the high price.

Fear-of-missing-out is more powerful than fear of losing.

In the investment world, greed and fear are the lifeblood. Without these, there would be no economy, no capital market, and no transaction.

Investments are not a lottery; if it feels like the lottery, stay away from it.
