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
