Well not quite the web of per capita energy usage eventually makes most activities quite even.

If you split energy usage into two parts energy to make stuff and energy to consume stuff.

On the consumption side most people are equal regardless of the industry they work in.
Next of course depending on the per capita consumption level you need X amount of core or industrial energy usage.

If you write poetry and grow all your own food etc then you make a difference. Just writing poetry alone really does nothing to change the equation since its your personal consumption not your output thats the issue.

Put it this way manufacturing cars is energy intensive. If you attribute this energy to each autoworker fine but to reduce it you have to reduce the consumption of cars by everyone. It really does not matter if the car consumer is writing green poetry about a beautiful world and is a vegan. He either must use a car or not.

And of course he can decide to practice what he preaches i.e say ride a bicycle but Jevons paradox ensures these efforts are at best symbolic.

I'm not saying don't work to reduce your own lifestyle and become both more efficient and self sufficient but unless it becomes widespread its a personal choice and ensures your lifestyle is buffered against shocks.

Its not wrong to do the right thing in your own personal life but its not correct to expect your choices to change society until it forms a significant minority.

Obviously I think the most important thing is to really work on your own supply chain if you will and reduce and shorten it and localize it. Withdrawing your own personal consumption is actually more important than the job you do. Its in a sense unfair to burden someone who produces wanted goods with the manufacturing costs and consider the poet someone special. Thats not the right answer.

And Joules I'm not saying your wrong I am saying that its the big picture that determines if a certain form of work or lifestyle results in a net reduction adopting a lifestyle is required but not sufficient to reduce the overall energy intensity of the system. Even your poet is sadly a Myth.
