Don't just give more stuff, give more stuff that people really want and appreciate. Have fun with your marketing, be proud of what you do. Affect others profoundly. Abandon the roles and job descriptions we all have. Whatever it takes, make an impact on your world.
Time is expensive, and wasting it is unattractive and irritating.
Thrive on the details. Pay attention to the subtleties, the small things. It's the little extras that build you up, and little slips that bring you down. Orient life around your values. Have fun with this list, poke holes in it, expand it, even criticize it, but think about the idea that your professional relationship with a client must begin with a good personal relationship.
