A steady income is crucial for wealth building.
If you want to be eligible for a bank loan or even a car loan, the banks will surely ask for your income statement. They will want to see if you can keep up the monthly payments.
If you are employed, work for others, then this should be covered. However, if you just started your own business, this might be a bit of a challenge as you juggle the companys needs and your employees. You might end up paying yourself last or not at all.
Whatever it is, for wealth building or asset acquisition, banks like a steady stream of income.
Make sure you get paid and if running your own business, make sure to pay yourself.
