Be careful and approach `HealthyGamerGG` with a bit of healthy skepticism. I have benefited from a number of his videos, but recently small things have lead to me growing concerned that as his reach/influence grows, the same motivations that existed early on mutate as with many influencers. Not suggesting anything negative per se, just recommending a variety of sources and validating his claims. For another source, Dr. Barkley's videos are very good.
