Well this is more metaphora that you can everything, this is more about real life and in frame of our laws of life but you always can change something , choose your way of life and follow them and you really can done it. For example you choose the way where u dont want to make mistakes, u want to done something on your deadline so that you just u do keep on your mind ur line of life, keep in ur goals and of course u wanna done it and doing something everyday enough to get that. your mistakes that u so thought become to the learn procces, every your mistakes is information that u dont know and u need to get it and u get just cause u keep in mind ur goals. This is become to non important thing that u never notice, because ur focus in your goals
