Odd one out...

[lazyknight]

So far this year, I've experienced a variety of changes that I really wasn't expecting at the start:

• I have an awesome girlfriend
  
• I have a new car
  
• I have a new phone
  
• I have cut my ponytail off
  

One of these is not like the others though... can you tell what it is?

I wonder what the rest of the year may bring?
