I once thought that stopping work before 50 would give me freedom. Instead, my agenda filled up again — this time with endless volunteer work. Full days, but not always full of meaning. And it hit me: Time is the only true limitation in life. We can always make more money, but never more hours. That’s why I treat my KasBook not just as a tool for money, but also for time. It helps me ask: - What really matters? - What can wait? - And what deserves my best hours? Because in the end, it’s not about being busy. It’s about being fulfilled. And you? Do you manage your time like money — carefully, intentionally — or does your agenda manage you?
