What a lovely story that really conveys the concept behind it.
I agree, although I suppose I'd word it a little differently, depending on how you define 'imperfection'. We all have imperfections, some we can iron out through actively trying while others are innate issues that we must learn to cope with or will take time to remove. Regarding innate imperfections, having them doesn't mean you can't utilise them. Maybe you've been through trauma and consequently sealed off your emotions, is that imperfection purely bad? No, it grants you assertiveness and the ability to be stronger in making difficult decisions.
I guess my point is I don't think we can make light of all our imperfections - e.g. if you have a constant desire to murder, as an extreme example - but those that we can't are usually the ones that can be 'fixed', otherwise yes you can make good use of your bad imperfections.
