This is related to a chapter in a book "Originals" by Adam Grant which I find also relevant to Trading (not Investing)
The basic idea here is that "the odds of producing an influential or successful idea are a positive function of the total number of ideas generated".
"Across the fields, the most prolific people not only have the highest originality; they also generate their most original output during the periods in which they produce the largest volume."
Shakespeare produced 37 plays, 154 sonnets in order to produce his most popular works: Macbeth, King Lear, and Othello
Mozart composed more than 600 pieces before his death at 35; Beethoven produced 650 in his lifetime and Bach wrote over a thousand
Picasso produced more than 1,800 paintings; 1,200 sculptures; 2,800 ceramics; and 12,000 drawings...
Edison accumulated more than 1,000 patents in which 15 inventions had changed the world
When it comes to trading, I found from my experiences that we should also need to try a lot of trade ideas in order to find a Big Winner. Out of 4 outcomes of a trade (Big Win, Small Win, Small Loss, Big Loss), only with Big Winners we could find success in trading. This is consistent with several trading principles for success as well:
Trading world is a Probabilistic system which over the Short term there is way too much Randomness. We don't know what will happen
Trading is filled with Uncertainties. You do not know whether a trade is going to make money. Sometimes we will win and sometimes we will lose
All we can do is to keep making Good Bets, a lot of good bets
We must honor our Stop loss to keep losing trades at minimum in order to stay in the game
We must ride the Winners which determine our trading success
