A short YouTube monologue (by Mark Evans DM) urging listeners to invest time in "mental fitness." The speaker recommends replacing music during walking/exercise with educational audio (podcasts, audiobooks), cites many hours spent listening, and claims stronger mental fitness makes other life goals easier.
I do urge you to invest lots of time in your mental fitness. When you're on that treadmill, when you're taking the walk. Shut the fucking music off. Drake will be okay for an hour while you fucking knowledge up. Get in the game of life. Do you understand? I don't even know how many tens of thousands of hours I've listened to audios, podcasts, books. But mental fitness, mark my words, is something we all need to be very aware of. I've been aware of it for a long time, because the stronger I make this, everything else I want, my life becomes a little bit easier here.
