Never go trade US stocks—otherwise you’ll be ruined. Because US stocks will just keep going up; besides making you money, there’s nothing you can learn. Once you’ve made money, you’ll get lazy, lose your drive, and turn into a useless person. You should go trade A-shares instead—there’s room for real game-playing there, and opportunities to dig in and research. Losses are what will fire up your ambition, and only debt can force you to go be a “cow horse,” working like you’re compelled to labor.
