Great motivations to overcome failure !

When u fail times & times and when every person indicates you as a shining failure, then still having belief in own self and not giving up is the mental strength, my friend. 

• When Abraham Lincoln became a failure in both business and being lawyer,he came to politics. But, here even he failed times and times to get several government posts. He was the most miserable person (according to him). Then, what didn't let him give up is the mental strength.
• When Thomas Edison lost first jobs for being non-productive and had thousands of failed attempts for making light bulb, then only his mental stength was left.
• Henry ford went broke five times and still could not give up. That was the mental strength.
• When Michael Jordan missed 9000 shots including 26 winning shots(he was trusted to take those) and his coach said that he can not be a basketball player, then that was his mental strength which kept him fighting.
• John Milton lost his eye sight and only for his mental strength he could write the Paradise Lost after 16 years of losing eyesight.
• Jack London recieved 600 rejection slip before his first book was published. It was his mental strength for which he could not give up.

This is called mental strength,my friend. Fail,fail, fail again, but u can't give up. And what takes for that is the mental strength.
