A strong business plan which ensures the sales and profits are sustainable and can cover the costs and ideally weather a storm, or nowadays a virus. In order to do such most likely, the owner and founder will need to take on ALL rolls in order to minimize costs. While not ideal someone with a multi disciplinary approach and business savviness may be able to be successful. When the sales allow for sustainable growth and the cash reserves add up, then it will be time to slowly (adequately) add employees who bring value and help manage and grow the business. Lastly, if it doesn't make you happy, don't bother. There is no point in working hard and making money if you're going to be miserable. Exchanging happiness, health, and relationships for success is never a good deal. The way to develop it is to be BRUTALLY HONEST with yourself about your weaknesses and your strengths. Play the strengths. Hard. Be merciless with your weaknesses by developing or delegating them.
