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))))
