METHOD: Make a list of your faults. Every time one occurs, put an "X" next to it. At the end of a day (week) you can see by the position and number of the "X"s, which are the most persistent faults.
If you remove the feeling or emotion from them, they appear just as mistakes. A mistake is something that causes unwanted results: wrong directions taken; accidents, miscommunication, ill health to mind or body etc. Seeing them without emotion is objective seeing. It removes the resistance to overcoming them.
The mind is like a computer (or more accurately a computer is like the mind). If you make a list and decide (program the mind) to do without them, you discover that every time you repeat a fault (or are about to do so) the mind will immediately remind you. If you respond positively to this reminder, the fault will disappear. If you delay, the reminder will disappear and you should note an extra fault "prevarication".
Generally with this project, you get the eye for a fault and can continually unearth ones you have overlooked. This is especially true if you can drain the feeling/emotion out of them. It's a lot of fun (and of course profitable).
