33 successful people, 33 short writings.
All good advices on what to do or what not to do - how to be remarkable, how not to disappear, why you should never stop improving.

As usual, the book itself won't explain why the ideas would work for you.
But the people who wrote them are pretty successful people, and that would validate their points.
Unless your definition of success differs, in that case, you can disregard the advices.

And if you want a short summary of the book, here it is:
Work hard, be brave, be creative, be nice, don't imitate, and don't give up.
Just dressed up in more words.

And one more thing, before I forget.
The 33 people sometimes contradict each other. They give opposing advices.
Is that bad?
No, not really. You just have to think, and create your own solution, decide what is best for you.
Sorry, you can't just get everything without any work. Not even with books.
