Add an artist to your circle of friends, or a mechanic who you can then share around. Lastly, make sure you look as good as you can. No shuffling or hunching. Even at the risk of coming across like a Barbara Taylor Bradford character, this is the way to build and consolidate power. Achieving power is different, however, from exercising it.
Powerful people can be ultra-stern task masters and shore up their power by doing so.
Mike Ovitz, the former Hollywood agent, apparently used to demand his fridge be filled with miniature bottles of Evian water. When an assistant filled it with litre bottles, he was not happy.

The habit only made him more feared. Once you have made it, others will worry about your moods or try to copy your personal style.
