He used ro sell bread to earn his daily bread And became an Engineer.

This is indeed inspiring. But many others also do this.  In Delhi, there are many young girls working as domestic help and also studying in college. 

Yes. Such people are Self made. They reach their cherished goals by their sheer mental strength.

True blue change maker is an ideal instance of inspiration for many. I know one of his friend during school days used to read down under street lights and used to circulate news paper and sell vegetables and now he is doctor, an honest person and when many denied to posting to distant villages he accepted happily. 

That's the characteristic of those who believe in their own strength. Success never evades them.

This is inspiring. People do that in life.  I have a friend who used to give tuitions to earn to do his engineering and to pay fees of her sister doing graduation.

Such people who made themselves by their sheer hard work and determination are the role models for the younger generation.  They are the jewels of the society.
