Because I read these three books. I suggest that you do the same.
Wealth building is 99% about behavior or discipline and 1% about financial wizardry or mathematics.
Day trading or picking stocks on the market is a stupid move because YOU can't, and nobody else can, beat the market. The mutual fund managers can't beat the market over a 10 year average, the hedge managers can't beat the market 10 year average, and the hot shot investors can't beat the market over a 10 year average.... except for a handful, and you already know all their names. Handful of people out of 7 billion humans on earth can beat the stock market. Good luck with those odds.
If you are building wealth for the long-term via investing, you can either get the market return or you can get less than the market return. Those are you only two options unless you have a time machine.
I have $15K IRA that play around with (no tax implications for daily trading), and even that is a stupid idea, which I justify by saying "it's for fun". Well $15K at the market return for 30 years is a lot of money, and it wouldn't be "fun" to lose all that money.
