No one is perfect. We all need to grow.
And growth occurs when we become uncomfortable enough with our present condition that we consciously take specific steps to change what we do not like.
Sometimes it may be a bad habit. Other times it may be something about our own character that needs refining. Regardless, change in a positive direction does not occur by itself.
Stagnation is the result of doing nothing. Degeneration is the result of doing nothing when we are continually exposed to negative influences.
But improvement always requires effort to resist the negative and be influenced by the positive.
