MassieIC, in following this discussion, I noticed the following:

You really don't have a good background for taking on bookkeeping as your business and that isn't what you expressed you want to do, anyway. So, don't do that.

You want to do food/food cart. That means the transition to having your own business would include you getting jobs doing that now, with other people, so that you can learn about food business management, they would pay for your need to be trained on health and safety and safe food handling (as their employee); you can observe various operations to learn what you like and don't like from "behind the curtain" and evaluate what you would want, for your own business. Having that experience makes it more likely you can jump start into your own business and not lose time on your startup; helps you have some frame of reference for setting pricing and sourcing supplies; see what it is like to have employees, regulatory reporting requirements, etc; and in general, get that experience behind you and not interfere or overlap with the issues of also trying to start up the business and the operation.

Because you have three considerations:

The business part of this.

The operational part of this.

The Knowledge for all of this.

Bite the bullet and take some jobs, even knowing the pay might not be what you would hope for, because they still are paying to while you learn, which is not a bad situation.
