Two popular theories of making change

From: Chris Guillebeau

There are two popular theories of change-making:

#1. Make small and incremental (but regular) changes. Mix it up.

#2. Do it all at once. Quit smoking immediately. Take cold showers. Enter boot camp for the soul—whatever you need to do, don’t wait.

For me it’s the combination of these two with strong inclination towards the number 1.

What’s your take on change-making?
