It is important to realize that the first steps are the hardest steps to take. There can be bouts with intimidation. There will be questions about your transformation.
Is this possible?
Can I do this?
Will I fail?
Will I quit?
More importantly, the real question is do I see any value in this?
Do I believe this could be me?
Will this be like every other time I tried to change my life?
Will I be great in the beginning, and lose interest as I go?
