Why do many get stopped in their tracks before they get started?
I don't mean just with smoking. I think many of us choose to underachieve.
My bet as to why based on my personal experience would be,
fear of change
fear of being uncomfortable
fear of failure
fear of success
These things keep most people from many opportunities in life.
(The first two kept me from going on the road with Elvis.)
What have you turned down because you were afraid of the unexpected?
There's nothing to fear about quitting smoking except what you create. Quitting smoking won't kill you.
It's continuing smoking that is the problem.
