A crutch can be cast away gradually.

Finnish has two verbs, ottaa "take" and ostaa "buy". As a n00b I confused them all the time. So I decided that the "s" in ostaa was a dollar sign, and I used that quickly in conversation to select the right verb. And as I got quicker at it, it became "intuitive". I threw down my crutch.
