(From bernard.matthaei@gmail.com) Hi there,

Read this if you haven’t made your first $100 from  bafilefamilychiro.com online yet...
 
I've heard it a million times...

I'm going to quit my job, I'm going to start my own business, I'm going to live where I want, and I'm going to live the dream...

Enough talk.

Everyone's got a vision.

Fine.

What exactly have you done lately to make it come true?

Not much, you say?

If everyone suddenly got injected with the truth serum, you'd hear people talk a different game:

I've got huge dreams. But I'm a failure, because I did nothing to make these dreams come true. I'm too afraid to start. I procrastinate about taking action. I will probably never do anything or amount to anything in my life, because I choose to stay in my comfort zone.

Incidentally, the first step to changing your life is to be honest about how you feel.

Are you afraid?

Fine.

Are you anxious?

Fine.

Do you procrastinate?

Great.

This means you have to start
