How strong is your belief?

Interestingly, everyone believes something - even the most belligerent person who claims s/he believes in nothing has a belief that there is nothing good to believe in; though won't admit it.

And, not "Do you strongly believe?" - A belief is something you already strongly believe.  A theory is something you're not sure about.
Weakness and Strength in a belief is about how good it is for you, and how much happiness it adds to your life; past, present, and future - in stable and uncertain times.

How does it prepare you and serve you no matter what happens?  A strong belief is bullet proof.  A weak belief is good right up until something unexpected happens, and it always does.  Here are some examples:

Weak: If I keep doing what I'm doing, then I'll get the same good results.
Weak: If I change what I'm doing, then I'll get better results.
Weak: If I go to college, I'll get a good job and enjoy it.
Weak: If I work hard, apply myself, and stay out of trouble, I'll be happy, healthy, wealthy, and wise.

Stronger: I know that I don't know or understand everything, I know that there are things I don't know that I don't even know that I don't know; in fact, the way the world is changing, I might not know anything.  So, I'll concentrate on the basics, try new things, and keep an open mind.

Stronger: I work hard, and I play hard.  I work at work even when no one is watching because character is demonstrated when you do the right thing even though you don't have to.

Rock solid: There is a hidden higher power in the world that makes everything right over time.  So, I will move confidently and humbly through life in service with joy, mastery, purpose, and contentment, knowing that every circumstance is provided for my good or for my training/preparation for even more joy later and greater service.

See how the Weak belief opens the future to potential problems and discouragement.  Notice how a stronger belief moves forward with a cheerful, positive, pragmatic attitude.  Notice how a Rock solid belief produces a good result, regardless of present or future circumstance - good or bad; if it is actually engrained deep in your inner self, it gives you great strength and happiness.
