Glad you lot like my posts 
WRT rethinking yourself as powerful. In general, I'd say women and girls need to hit stuff more, have you ever booted a football for miles, or really smacked a rounders ball? That, every week of your life. And loads of overam throwing. Squat to get stuff instead of elegant waist bending. Notice the many powerful movements you make on a daily basis, I carry the shopping up the stairs to my place, that leg action is very powerful. Notice yourself breeze through heavy doors. Most people actually have to restrain themselves from smacking doors open too hard.
I think there's nothing like really learning to fight, though. Getting smacked in the face and not falling over and crying is huge, life changing in fact. And learning to fight with a weapon like a stick or staff, means every room with a broom in it feels totally different. Everyone is deadly with a weapon if they know how to use it, strength is almost immaterial as compared to technique. DP is a martial artist, he's good, he does a weaponless form though. Which means if there's a weapon in the room, I win. Even if there are two, and we start with one each, or he starts with one and I'm empty handed. I can take his off him and he's fucked. Brooms and other lengths of wood - chair legs, sports equipment, anything heavy in a pinch, all make good weapons substitutes.
