Throughout our life we always face with the ups and downs. We need to prepare ourselve to strong not only physically but also IMPORTANTLY mentally.
I would recommend to whom who haven't read the book on "The Magic of Thinking BIG" to get go and get it. This books will really change your perception on what you can achieve in life.
Especially to people who seek ways to be more confident in life (like me hehehe).
"How big is the problem is how your mind think how big the problem is....." ;)
