if you are trying to figure out if it is a simile or a mediator, look to see if it used the words "like" or "as". If it does, it makes it a simile. If is doesn't, it makes it a metaphor.
For example:
"Life is like a box of chocolates" is a simile because it uses the word "like".
"Life is a box of chocolates" is a metaphor because it doesn't use the words "like" or "as".
So, the sentence you put is a metaphor, because it did not use the words like or as.
