Everything has a purpose.
Everything can be of use to us or not, depending on how it is applied. It can either take us towards what we want to become or take us away from it.
In some circumstances it might be exactly what we need. And in some it might be downright harmful.
We have to identify when the time is right, when certain actions are appropriate.
On their own they are just tools. Nothing more, nothing less.
The value comes in knowing how to use them.
