Quote from Manieu:
Just take one big gamble instead of trading for years... because otherwise if you trade properly it would take years before you have $100.000,-.
If you read Fooled by Randomness (i think that it's in this book) he explains how you should just take one big gamble if the odds are against you: i.e. 0.49 chance of success or lower.
But if the odds are in your favor (0.51 or better) then you should play the law of large numbers like the house does in the casino.
