"Any change, even a change for the better, is always accompanied by drawbacks and discomforts."
-- Arnold Bennet
This just lets us know to be prepared. Change is inevitable and it is never easy. There are drawbacks and discomforts. Most of the discomfort comes from our strong desire to maintain the status quo and from our fear of failing or the fear of succeeding. This is no reason to resist change. The drawbacks and discomforts of remaining stuck in old ways of doing things will far outweigh the discomfort of change in the long run. Overcome the fear and embrace the concept that life is about change.
