Things I've mastered with just my left hand:

• Taking a one armed shower
• Washing my hair
  
• Brushing my teeth
• Eating a bowl of cereal
• Typing
• Getting dressed
• Emptying the dishwasher
• Folding laundry
• Using a computer mouse
  
• Putting the water jug back in the fridge (its a process: open the fridge door, hold the door open with your foot, spin around and reach for the counter, grab the water jug, place in fridge, close fridge door)
• Putting on shoes (Ha, do clogs count?)
• Making the bed
• Using the remote control
• Using toilet paper ('nough said)
• Opening and closing the passenger car door (think about it, you always use your right hand to close the passenger door, so left hand is pretty tough)
• Using my "straightner" (flat iron) on my hair.
• Updating my blog
