Why people fails

I have deep talk with my wife with some several issue ( lets say events ) recently and how to deal with it with healthy way. this is my two point for overall responding.

1. any Issue/Events failure rate are not related, almost every event are separated. even it seems like related — but just like throw coin.
2. you only can control your self. not else, not you parents , not your friends, not your child. only you, but you can control you self 100% ( right? ).
3. once you accept this two point you will be (almost) bulletproof. enjoy!
