Slava

It's entertaining and inspirational, but it doesn't contain much practical information. I was expecting more info from the developers on the process of finding an idea, implementing it, and marketing.

It's a soap opera actually, but very well written.

Boring and useless. Couldn't read it until the end, but looking through it I couldn't find anything of practical benefit, only a number of stories repeated in different words throughout the book.

Good for beginners.

I've read only half of the book. It contains several useful ideas. But there is so much boring and common sense stuff, that it's hard to push through. The first part about author's life is meh. The second part about life principles is ok. I've decided to skip the last part about work principles, as it's mostly not applicable to my current life. Maybe I'm just not the target audience for the book, which is I guess higher management and owners of large companies.
