I have always liked SRK, over other actors because of how he treated his wife. Anybody can act. Its not rocket science, or curing cancer. But to reach that level of success and yet treat the people close to you well, and not get distracted by success - that takes a separate level of moral grounding. I like KP Singh for a similar reason. His devotion, and attachment to his wife, is clearly seen in the book. His humility and frankness is admirable. I liked one line in the book (not exact) - "there is no defined ten steps to success, there are just baby steps". He portrays a realistic picture of success, of an uncertain path, where you just have to keep soldiering on. Reminds of me Nietzsche's writings.
Edit insertion** - I wish I had his Army Discipline. Hopefully, in the future, I can replicate it.
