Business and any business grows in the following way. You run like a squirrel in a cage. Then, with incredible effort, you move to a higher level. And your income increases. Then you run again. And again you perform a feat. And again you go to a higher level. Each energy level corresponds to its own stable income level.
You may often hear that smart and skillful people have to work for the stupid unskillful. The reason is that no one wants to hire stupid useless people and pay them well, so as a result, they have to figure out how to survive and start their own business.
Any salary no matter how high will be fully wasted by the end of the month.
There are only several obstacles to prevent wasting the whole salary before getting the next one, namely physical lack of time or saving up some money right after getting the whole sum at some inaccessible place.
If you want to get a raise in the salary-first very well and work hard, and having achieved perfection and admiration of the authorities, quit. People have little value for what is good, but the threat of possible loss forces them to reconsider their scale of values.
