I believe in alternative ways. It shade some lights of freedom. How do you know if you like what are you doing when you never consider alternative ways? Nowadays, alternative ways are like luxury. But it's just because you don't know how to design, or even think about it. Worse, people who should have been able to think never do and keep asking the same question. I don't know whether what I do is right but at least it a trial. What do you expect at the end about what the difference? How do your legacies or footprints matter if they are just the same? How it helps humanity for better if you do what have been done for thousand years and still plenty of problems, or worse? Keep expecting differently while doing the same is absurd. Don't thinking about or pretending to be non-sufferer are probably worse, because thinking or talking about it is the best we can start. Again, I also don't know. At least I know that. And I keep reading, because it's most economical way of pursuit. Some said tacit knowledge, even in forms of demonstration, is available now. What you need is just some logic to interprete. Let the bell rings.
