"If you need a degree to do it, it’s not going to make you wealthy."

If you need a degree to to get a job , anyone that takes that degree can do that job. You are going to do just ok.

If you have a soft skill you probably can do very well. Examples:

If you want to do whatever you do well/Conscientiousness

If you want to finish things. Check

If you don't like to multitask

You beat any University degree 100 to 1

Conscientiousness is the personality trait of being thorough, careful, or vigilant. Conscientiousness implies a desire to do a task well.[1] Conscientious people are efficient and organized as opposed to easy-going and disorderly. They exhibit a tendency to show self-discipline, act dutifully, and aim for achievement; they display planned rather than spontaneous behavior; and they are generally organized and dependable. 

I am an economist by training 

I forgot everything that I learned to pass the exams. 

Perhaps one idea remains and has been useful , very useful. Too much of something doesn't work anymore, if you drink a glass of Coke is nice, the second ok the third is difficult etc....

In the ecomomy it's exacly the same thing, if you have too much debt it stops working and we are there. after we reach 100 or 200% deby to GDP more debt destroys growth etc...

this idea declining marginal returns is true in pretty much everything

 Great rules but nº7 is key, not possible to move forward when only one group is advancing, if everybody is advancing some more than others everything is good.

It takes the energy equivalent of 100 barrels of oil to fabricate a quantity of batteries that can store the energy equivalent of a single barrel of oil.

Transition to the Poor House

The solution for all the problems is technology

Physics is the solution 

The way we live , the quality of life we experience is due to Hydrocarbons . If we want to transition to an inferior solution our life will suffer. 

Batteries are not the solution because they are very expensive to build and don't last long. Some people say they are not very good for the envoirment after their useful life. You need 100 barrels of oil to build a battery to store 1 barrel of oil! of course we could buy a tin barrel that cost USD 1 and last forever to store 1 barrel of oil .

Energy consumption grows every year. That is not going to stop.

The great beneficiaries of the Green Agenda are the Saudis & Putin.
