when i learned hiragana (and katakana), i just wrote them over, and over, and over again until my hands started bleeding
. after a few weeks of starving myself until i could write them perfectly, i was sent to the emergency room for emotional ecstacy.
obviously (i hope), u noticed that was hyperbolic. but i did write them over and over again. also, i suggest u read more texts and type japanese on the computer. it helps.
