I have had some thoughts on point 18 again. When a good market comes, it is time to place heavy bets, and operate with the mindset of 'I want to make a lot of money,' aiming for a big profit.

Always playing with the mindset of earning living expenses or investment returns, or thinking that there will be many more opportunities, and then only investing a little bit, often results in not making much profit when the right outcome is achieved. It is really a waste of opportunity and time.

Then I reviewed what my brother said, indeed! It is always new when you look at it often.
