"We are what we repeatedly do. Excellence, therefore, is not an act but a habit."-Aristotle
Have a think about what you repeatedly do and that you want to continue, and do more of that! And become excellent!!
Anything you repeatedly do that you wish you didn't? Recognising those habits, the triggers and remembering at this point you can choose how you act, helps change the habit. Small steps towards this are just as significant and just stopping. Be pleased with your positive changes.
