Stay in your own lane and perfect what you know. Realize that every strategy has strengths and weaknesses; there is no perfect strategy. But once you know all the pros and cons you can perfectly execute your strategy... and that's the goal.
I don't know shit about 99% of the stock trading strategies out there... but I know everything about my strategy. And that's all I need to know. I realized long ago, you can't be good at everything. I'm an expert because I chose to specialize. pic.twitter.com/uG7gWwhsjs

Visualize what you expect to happen and how you will react. More importantly.. see in your mind what can go wrong and how you will react. Make this routine contingency planning.
According to your 3rd book, could you please explain how to practice visualization in trading? @markminervini

Not every trade works out for me. Far from it! I lose half the time. But EVERY trade is a good play at the time, because my risk is always a fraction of my likely reward. And that's the secret... I always get odds on my money. In trading, that's the definition of a "good choice."
In any performance business the bottom line is winning, hitting the goal, getting the job done. Winners do what they have to do to win. Losers make excuses why they didn't perform. A way to win and a way to lose ALWAYS exists. It's a matter of the quality of the choices we make. pic.twitter.com/RXvu4o4FBC
