How do you keep track of everything on your own with client projects, students, and promises, and doesn't it get overwhelming?

Yes, it definitely gets overwhelming; I have overwhelming days like anyone else. Even the big business titans I admire have extraordinarily overwhelming days, though they hide it well. The feeling of overwhelm exists on a gradient between no stimulation and overstimulation, with an optimal middle spot where you're optimally stimulated—this is the ancient Greek concept of ESS (optimal performance zone). On a stress‑meter graph, the sweet spot is where stress brings out your best performance; high performers operate there, while being over‑stressed (distress) is too much and harmful. I often feel overwhelmed and admit my project‑management systems aren’t the best, but I’m working on them. The key idea is to treat your limited daily time as a constraint and use it for good—find ways to do the same or more work in the same or less time rather than seeking more time. I appreciate the question and note that many one‑person businesses make more money than I do, so I look to adopt their systems. Simple systems that keep things on track are a big lever; publishing content every day is one of them, letting me answer questions and create content simultaneously—killing two birds with one stone. When a student asks a question, I record a video to answer it and also produce content, always looking for opportunities to combine tasks. This approach yields more creative output, a stronger content strategy, and higher volume—a tactical way to work.
