Reflection about the Top 5 Ground Rules from Buffett

1. Never try to predict the market
In average, around 1/3 chances the market trend is up, down, or no moving.

2. Investing in the "Deep Value"
Deep value is still quite art for me. Everything is uncertain in real work.

3. Approach investment with a long-term mindset
Always plan for long-term investment but always ready to sell out when it is overvalued.

4. Have something to compare against
More companies you have studied, then more insights you have about valuation.

5. Pay attention to the compound interest

Flat rate interest is around double when we calculate its effective interest rate. Upfront fee 1% for a zero percent of BT can be around 2% effective interest rate.
