Is it bad practice that I use some mnemonic devices involuntarily when learning kana? I have been drilling hiragana these past couple days and I can't help but think of related words or characters I already know.

For example, when I look at らI think about Araragi Koyomi (because of the "Arararagi joke"), は reminds me of a mother, ふ reminds me of vapor for some reason, る for 'To Love Ru', ゆ for Yu Narukami, etc, etc.

I doesn't happen with all characters but I wonder if these "crutches" will hinder my progress later on.
