If you are trying to meet a good standard of living, you may never save or invest. To save and invest, in most cases, we need not even consider the standard of living because the goal is to save and invest to reach another financial level.

I would say that to improve one's financial situation, one should seek more sources of income; however, one thing about the standard of living is that the more income and financial stability one gains, the level of financial living also increases. The main goal is to concentrate on saving and investing, because if you focus on improving your financial living, you may end up not saving or investing at all.
