People are often clear about a goal. At the same time, they are not clear about what achieving that goal will give them or do for them. Nor are they aware of how reaching their goals (weight loss or otherwise) will change their life as they know it.
You can achieve clarity by stating a goal.
“I want to be rich.”

Now ask yourself:
What will achieving this goal do for you?
A: It will give me financial freedom.

What will financial freedom do for you?
A: It will allow me to quit my sucky job and travel.

What will traveling do for you?
A: It will broaden my horizons.

What will broadening my horizons do for you?
A: It will make me feel better about the way I live my life.

What will making you feel better about living your life do for you?
A: It will make me feel good about myself.

What will feeling good about yourself give to you?
A: Self-confidence

What will self-confidence give to you?
A: Freedom to be me.
