Life is smooth/peaceful and easy-going till the time a wave of bad luck or adversity shakes us from top to bottom.
Even though there is very little that we can do about avoiding any such incident from happening, there are things that we can do to come out from this failure atleast mentally. The way we approach failure and act upon to come out of this, defines how successful we are in life.
We all have goals, targets that we want to achieve and we work hard towards it. During our struggle to meet our goals, we succeed at times and at times we face very sever and adverse failures, but then that's not the end of road. Some people fight back and many fall in the traps of circumstances. The one who says that "I might have failed but I am not a failure." and stand up to walk all over again, is that one who goes on to redfine success for him self.
It is not wrong to fail, but it is a crime if you don’t get back up again and try. The successfull people are the ones who have tried till the time they had succeeded. Remember success or failure is not an event its a process, its a journey, its a series of events. So a single event of failure cannot make a failure person out of you.
So If you are feeling depressed and sad because you have failed and hit the wall. Remember, the only way out is getup and try again, your next attempt is going to be better than the previous one.
In the words of a great person:
"Life is a series of experiences, each one of which makes us bigger, even though sometimes it is hard to realize this. For the world was built to develop character, and we must learn that the setbacks and grieves which we endure help us in our marching onward."
