What will I do if I could turn back time ? It depends on what knowledge that I have.
With my past knowledge, I’d change nothing. I’d do everything exactly on the same way.
With my present knowledge, I would not do every single mistake that I’ve made. Maybe I’d do another mistake, but I don’t need to worry ‘cos I have time machine. Hehehe.
But the most important thing than playing what-if game with the past, is how to learn from the mistake.
