Saving is for the poor. When it comes to large sums, saving means wasting time. It's enough just to watch that expenses do not grow, and efforts should be focused on income. I do not like the word "save", I immediately see the hungry years, the war, the "great depression", etc.
The difference between a business minded man and a normal guy is that the business minded one doesn't like saving. Saving for him is just letting his money sit there. If you give them the same job with the same salary, eventually, the business minded man will resign because he has made enough money to go to the next level while the normal one that has been saving his money will just have enough money to buy the stuffs that he want to buy.
Most of the people that succeed in life didn't rely only on their jobs. They invested in assets, in starters projects, etc. They simply look for opportunities to make themselves grow, and grab that opportunity.
