The criterion for choosing a business is whether you can do everything from beginning to end.

As long as all costs are controlled within your own food, clothing, housing and transportation, then the costs are very controllable.

Then this business is a very good business.

If you need to rely on this, that, and need a team, it means that you do not have the ability to do this business at the moment.

Only when the annual income and profit are very large, you need to consider the team.
