I'm a huge procrastinator. I procrastinate EVERYTHING. Huge weakness.
I am lazy, and it doesn't help that I can get DH or even sometimes DD to do something for me like go get something out of a different room.
I hate being around people that talk like General Relief Society Presidents. My current RS President is one such person. She really grates on my nerves just because of the way she talks. It sounds so fake to me, although I know it most likely isn't.
I hate saying anything in a group setting, I get all shaky and unsure of myself...therefore I never speak up in SS/RS, or very very rarely at the book club a few RS sisters put together. I just sit and listen. I can hardly pay attention during Sacrament Meeting - if Melinda's behaving herself, then DH and I will play a doodle game to keep ourselves awake.
I pretty much don't control what I eat. If there's a bag of candy and I'm not paying attention, I can eat the whole thing in one sitting

Such a big sweet tooth!
Scripture Study/Prayer - DH and I have finally gotten to a point where we're reading our scriptures (almost) daily together, and we now have family prayer when we're putting Melinda down, but I still don't say any personal prayers unless I'm desperate, and I don't really "study" the scriptures, I just read them...and maybe ask DH a question if I don't get something, because he usually does.
I have a short fuse, as well, when DD is being crazy. If she starts hurting me because of being crazy, I will yell at her and I always feel horrible about it, because I know if I were doing something more interesting with her, she wouldn't be acting so crazy. But there comes the lazy part again - it's so much easier to sit down than to be creative and come up with something interesting to do.
There's a lot more I could include, but those are foremost in my mind. Nothing like putting it all in one list to make a gal feel guilty, lol.
