Just finished taking a shower, I came up with a book that made significant impact on my life. When I was in high school, I saw my close friend carrying a robotic book around since he was into robotic competition, it woke me up from just singing some rap songs. I was like .. I had to get into something cool in sci-math field, then that day I was in computer class that taught Microsoft Office stuff and save work in floppy disk. At that time I just know programming exists but had no idea how it actually works. I reached out teacher and asked "please teach me programming", he said like .. nah getting good at Office stuff I taught you first. That's fair but I wanted to be as cool as my (robotic) friend. I went to a book shop, picked up a "Programming C" book and also bought "Turbo C++" CD. That is the moment I know what major I was going to get into at university.

So the book that actually probably changed life quite significantly is my friend's robotic book that I didn't read.
