"NO" is not always "NO"

You see things; and you say “Why?”
I dream things that never were; and I say “Why not?

16 years old, I had my first income with the idea to buy error 1.4MB discs at the video game shop (1K/ disc) then fixed it and resell to my classmates for 7K, haha

20 years old while studying electronics at Hutech, I built a commercial device for the micro controller 89C51, the profit was not good but I learned my first lesson of negotiation when dealing with the supplier, yeah that was really good and fun experiences for a student with no money like me.

Thanks God to bring this memory back to me, almost forgot it for a long time. Life is so tough.
