Give your ambition a name.
You should be on a first name basis with your ambitions. When you name something you establish a relationship with it. You open a dialog of sorts, in which you treat the other entity with understanding and respect. Your ambitions are not an extension of you: they exist separate from you, have “lives” and conditions of their own, and are shared by others. You are merely trying to be their friend. Seek out a good ambition as if you were seeking out a mentor. Be grateful when your ambition decides to take you under its wing. Perhaps with time, the student will surpass the teacher.
