Here's something I've been thinking about recently ... how much is change affected by events or desire? Do you think that people are genuine about change internally, or do events dictate change within oneself? Personally, I believe that it's a mixture of both, but since change causes stress ... which is the human condition, I think that events have more of an influence on people initiating change. Desire is a powerful motivator, but since desire is internal, people are less inclined to act on desire alone.
Consider this: If you've ever been in a situation which mandates change, such as quitting smoking, is it because of a change in work policy at your place of employment, a rise in insurance premiums, or something like that, or is it because you know that smoking is dangerous? Or is it because your doctor told you that you have lung cancer? Or is it because you've just met the love of your life, who is a non-smoker? Or is it because of all those ads on tv?
How much control do we as human beings have over external factors determining our actions vs. self-imposed desire for change?
