If you want to have a full, educated, interesting life, you need an open mind.  You need to be open to experiences that make you uncomfortable.  You simply don’t know what you don’t know.

If you start these experiences with thoughts (or words) like:

Yeah but,

I won’t,

I can’t,

But,

It won’t,

Never,

(or things like this)

You don’t have an open mind.  You should change that.
