1. The rule is always do not bitch about anything because it is not going to help and it makes you look bad, upon certain age we learn to deal with it the way it is. Life sucks, and you take it that way because it gives you better odds at changing what you don't like, or you can deceive yourself to feel better for the rest of your life.
2. The problem is not the lack of energy nor talent, but focus. You need keeping yourself occupied so that you don't have to deal with things you don't like, whereas in the end we all know the reckoning day is coming. 
3. Again concern not with things you have no control over, but over the best possible play that gives you the most favourable odds amid uncertainty.
4. Good Food, Good Sleep, Good Workout. Mind = Body, it makes sense.
5. Time to review the letter to Rose again, well why the obsession though you might ask, but then, I just felt that this is something I never had the chance to say. She got a new boyfriend, life is well for her. Eight years, people say we should learn to let go. I don't know, she probably doesn't care at all, but the letter deserves to be read. Things did not end well, and sending the letter out soothes the ending, at least on my side.
6. Prayers do not need to be answered to be effective.
7. Nolan said real movies don't have post-credit scene, I felt it is a fair comment, and Chinese interpretation is

Marvel: 套戲其實仲未完, 你地想聽先講.
Nolan: 真正的男人不會想講又唔講.
