If your happy,  
don't blow it. 
If you've blown it,  
don't show it. 
 
If your sad,  
turn over a new leaf. 
If the other side is also depressing,  
Try and show no grief. 
 
If you are angry,  
breath in breath out. 
Find out what it is about,  
take a different route. 
 
There are three sides to a coin,  
front, back and the rim. 
If your standing on the edge,  
don't fall if you can't swim!
