Fight for password!

I really don't like it when I can't get into my accounts! I have made the same passwords for some and different ones for others and can never seem to remember which ones go where! For example, Google locked me out of my blog yesterday and I changed the password. Today, I sat down to blog and it locked me out again, I even used the new password and it still wouldn't let me in! I had to change it yet again! UGH!!!!
