Sometimes you've got to just say fu** it,  let's do it!  
What are we waiting for?  

Everybody says 'it's all downhill from here' when you hit 21.
Before that its first kiss,  first drink,  first relationship,  first job etc..
But what's after it?  
Adventure
It's new experiences,  it's opportunity,  it's love,  hate and everything in between.
If you have something you've always wanted to do, why wait?  
Go and do it
Life is too short to regret not doing things.
Go out and live
Leave tonnes of memories behind.
