I agree with you on mistakes. I believe that as human beings, mistakes are unavoidable. You can make all the preparations and try to be very careful. You can even try to avoid making mistakes but you will not win.

Sometimes we make mistakes knowingly, but we can also make mistakes as we try to make things right. In your mind, you will be doing the right thing and you will be justified. In real life, on the other hand, that correction may be your biggest mistake ever.

So, the best way to deal with mistakes in my take, may be rather unorthodox or unacceptable. But I believe that there is no need for anyone to regret making a mistake. Its impossible to go back in time and fix it anyway. I think the best way forward is to sit down and reflect after making that mistake. That reflection will help you calm down, come up with solution and then learn as well as improve from that mistake.

This is my humble take. What do you think?
