Chasing Dreams ... how far would u go?

Today is about 2 persons who are chasing after dreams...

The first one, is a friend from north. Let's name him Eric. He wants to be a master instructor in taekwando. He wasn't inform about the closing date which was on 1st of May... He felt cheated as not being informed by his trainer. However, due to his determination and his believe in achieving his dream, he braved all obstacles and he managed to get to the designated place...

The second person is a lady who is trying to earn a living. There's nothing wrong in that but when she starts to disrupt others or backstabbing other just to achieve her dream that act itself for me is very very wrong.

The question is how far would a person go so as to achieve his or her dreams?
