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.
Yes, this is a valid point, mnemonics are totally valid when you are new to a concept.
I'm learning Turkish right now for example, and the dative forms for me/you (bana/sana) perfectly fit the accusative conjugation pattern in my native Polish. So my mnemonic is explicitly "the opposite of what you feel it is".
