Repeating the same mistake 20 times tells me that person would be better off getting a job rather than trying to run a business.
Hire the best you can find and afford. That’s a critical rule for a small business. The small business that goes with the less costly employee with the hope of ‘developing’ talent will only waste money. While it may feel noble to give a chance to someone lacking the necessary qualifications, it’s a mistake. The large business can afford it, perhaps. For a struggling small business to hire someone based on lower cost could bring the business down.
