Passwords and passwords!

Grant me a rant today!Its about these things called passwords.Sometimes they work and sometimes (which is NOW) it does not.I am a meticulous sort of person who jots down important things and something like a password is top priority.So why does my gooogle password always get bounced off?If I ask the HELP assistance side,they don't give personal replies.This is sheer frustration especially when I have something to rant about.Being able to rant now is because they(who-o-o????) decided to accept my password....this time around.I wonder if it will work again!!!#^**!!!
