Life will be easier to live, if we value mistakes as a time to learn.
Take the wrong train? so learn the right route;
Misdirected message? be more thorough:
Wrong pronunciation? so learn english
It's okay to make mistakes as long as you learn from them
Tulus said in his song:Kecil hanya sekaliMuda hanya sekaliTua hanya sekali
You have only ONE shot at life. Do you want to spend it stressing over every single thing in the past or focus on the things you still can control instead?
The conclusion is that mistakes are a human thing, anyone has made mistakes. What must be done is how to prevent these mistakes from happening again. Mistakes can make a person learn, grow and improve themselves. Remember that time and experience can be great teachers for learning.
