Usernames & Passwords
Two of the most controlling elements today. Anytime you have to access things that are important to you, these two guys always show up. I'm waiting for the moment to arrive when I go to a public restroom and I am asked for them there. Although, I am suppose to have all of this info put away somewhere, I need a password to find out where I placed them. I went through a scary moment a few days ago when my computer crashed and I lost all of my files. It was not a fun moment.
Because of my local networking connection, I found a place nearby that was able to recover everything. I couldn't believe it. These guys were great.
I am more adamant at backing up things now.
