I'm considering using Fridays to share recommendations to podcasts, videos, and articles. While I continue deliberating, here's an old post that describes three strong podcast episodes (and here's the follow-up where I belatedly provided those links, and offer a sarcastic editorial comment about global warming).
These three ideas have stuck with me. The cash flow concept is particularly relevant today due to the way COVID-19 induced lockdowns have instantly shortened the time frames for many businesses. Most ventures are viable in the long-term but the rent is due tomorrow; any fool can calculate 'profitable' (hint, revenue minus cost, hint) so why do so many businesses fail? My gut suggests that if I could only use one quality to assess a person's ability to run a business, I would pick the person's understanding of cash flow.
