Is Failure a Mistake? Ask yourself
Failure is never prone to be by mistake but by poor effort. People tend to attribute their failure to their mistakes which is wrong.
Note, that it is when you strive and trying your best to achieve a goal but later miss the goal is term a failure probably due to limited effort therefore, you need to put more effort and try again and try again. And one day you shall reach the peak.
Your mistake results from your inattentiveness towards your goal. You don't even practice talk less of putting effort then this should be termed your WANT. At that stage, you don't want the goal yet that is why you didn't put any effort. So you lose nothing since you put no effort. The Mistake is simply your want and not your failure.
In short, it is when you put effort that failure and success could result while mistake comes from when you don't create a goal and you don't have any effort sacrificed.
