Not being able to see the face of the person who does the stupid thing also has a massive impact on how people think of the other drivers. Similar to how (most) people who would chew someone out over the phone will hesitate to do the same in person.

My phone support days had way more customers willing to be nasty than any of my retail jobs.

For me:

1. Set goals
2. Accomplish those goals

That’s what gives me the best feedback. The more realistic goals I set and the more often I accomplish them, the better I feel. Bonus points for setting “due dates” for bigger goals and seeing if you can meet your own deadline.
