The first two examples that are cited as evidence are companies who he noted as failures because their stock dipped in 2007-2008. Cherrypicking evidence from a decade ago, and correlating it with the massive market selloff... I couldn't continue to read the nonsense beyond that.
Strong convictions are the optimal way of wielding influence. The people paying for their time don't want to hear caveats, they want to hear that their dollars are being maximized.
Usually stuff without lyrics, or lyrics I can't really understand, so the songs remain in the background. Anything to drawn out the open office setting when I need to concentrate, and also to pump me up. Seems like repetitiveness can help reduce distraction.
