Listen to others but chose wisely.
While I am listening to these books my mind start to set that as the reference to the reality and start to give suggestions around how I should change myself and it is automatic.
You can listen to books, and even its ok to have the voice it is quiet temporary. but then you need to slowly integrate in your daily life.
Listening to different kind of people as mentor is a great idea to pick their brain and see what they are doing, listen to their advice and see if you want to integrate it.
Build this muscel when you are listening to other people, paying attention, seeing their reasoning, not taking it as a truth, not being defensive, but putting your reasoning infront of it. practice it over and over again. other people will most likely become defensive and aggresive.
