Why are mistakes and failures good?

I plan for participating in Software testing training at Logigear after I read an entry from http://quynhxq.blogspot.com/2010/04/vv-tham-gia-testing-training-tai.html . In this article, she shared her experiences when she was interviewed to be accepted for taking part in this program. She wrote very detail so I think I will follow those things to learn.
Now, I have a freelance at Sutolym working as software testing. I am in software testing bootcamp and I learn the very essential and interesting things about software testing. I have chance to approach knowledge relating to software testing and now I learn "Specifying functional requirements with use cases" and using it to design use cases for a reality project of Sutolym. It's so much fun and I must complete my task as possible as I can.
And I will send my CV to Logigear after I finish all my tasks to reach the essential knowledge for testing to pass the interview, after I really know I am ready for the interview.
I will take part in the Toiec examination in the space of August, 15th . The expense for this exam is very expensive so I must try my best to pass.
:) So, planning to pass Toiec now, I think you have enough intelligent to pass easily.
Don't be afraid of mistakes and failures!  Just try again like the time you were a little girl who tried the first step to ride a bicycle. Read part 6 of this article Things I wish they had taught me in school make me laughing out loud because I remember when I began to ride bicycle. Between times, My parents had not enough money to buy me a bicycle so while my mom have being worked at Ba To's hospital, every day my mom went to work, I followed her to hospital and I borrowed any bicycle I seen from my mom's co-workers that I know to practice riding bicycle. You know that, my hometown's hospital is very small and has place for me to ride bicycle. I even couldn't sit on the bicycle's saddle but even in the middle of day, in the horrible-hot sunshine, I still keep myself to ride, just ride, just ride. It was seem a fun and happy thing for me to do that. I remember I didn't feel any tired, I were just happy.
So much fun when you ridden a bicycle in the hot sunshine, in 1pm on the tropic country, everybody said that Are you crazy? Why do you do that in the horrible condition? Oh, sometimes instead of borrowing a nice bicycle I just borrowed a "Đồng dông" bicycle ( I can't find out any words in English to name this one, this bicycle has a bar which blocks of the bicycle's body). It feel like :

This one is very high, now I don't know why I could ride on it despite I fall and hurt so many times.
So, I will face this present life with that positive opinion. I will try again, again, again with endless enthusiasm to archive my goals and to be happy with the things having so much meanings with my own life.
