Accepting mistakes emphatically save a lot of time but who would do such a thing..! In the end, a mistake is always a frowned upon and that is why we avoid admitting to it. With that said, mistakes are inevitable .
Mistakes are the basic building blocks of learning. I remember the time when I first sent my email, “the first official email” in TCS. I remember reviewing it for half an hour (since I was communicating with the senior management in that mail) and I also let my peers review it. Unfortunately, the moment I pressed the sent button I realized a grammatical mistake.
Alas, it was too late.
Since then, I have sent numerous emails and have made many mistakes, but with each one of them, I became more confident and more expressive.
