Well, at 60 it’s a little late in the game to be thinking of things I should have done by 30, not to mention it’s depressing to think about.  So, to answer one of the questions, no that is one book I surely don’t want to buy!

I haven't seen a book like that but I have seen a lot of articles taking about similar things such as: places where you must go before 30, things that you must experience before 30. Anyway I'm not interested in it. 

I'm interested to hear what kind of things are listed in these books :) 

i think this is an interesting book,i want to know the list, then compare my life with this book .

DAICHI, I could only write such books now, not 'read'.

I don't see why 30. "Love", "thinking", "creativity" seem to be good ideas. In any age. Well, it is good idea to take your own ideas very seriously when you are a teenager. Because good ideas do come, people have brigheter imagination - but certainly are lacking confidence.
But I said "own ideas". If I write which ideas that would be stupid))))
