Lack of patience.. I am not a good teacher

i hate to teach.. but unfortunately, i can't get away with this.  At work or at home... I've been guiding people a lot with computers and internet.  Now, as i grow old, i become really impatience with it.  People are not taking initiative to explore and that's the reason why they don't know or will never know how to use a computer.. Argh.. it's really frustrating and I can't stand it.

I'm now having to guide my eldest sister to blog.. she is so confused with emails and etc... and worst of all forgetful.  How can i remind her with her password.. aduiiii.. pain
