docile or not?

My sis keeps telling me, i should not try to be rough.. play down my fascination for my taekwondo, try to be more gentle, actions softer a bit.. say i shoudl try tactic..

boy. that's going to be tiring. the truth as i've faced it, is that i can never be gentle or soft or whiney like the typical taiwanese girls. and i have a male friend who tell me i'm a bit too strong for my own good.

Now, should i just be myself? or is there reason that I should change ?
