RE: Owning your own shop?
I would recommend taking Cost Accounting, Financial Accounting, and Business Tax classes while at school. That should be sufficient for you to learn the money management side of things - understanding financial statements, cash flows, costing systems, cost allocation. Everything else has been said. Work in the archery business to gain a customer base who respects you and save save save your money. You'll incur a large amount of overhead cost just to open the doors initially - building (rent or buy), building renovation, fixtures/furnishings, equipment, utilities, inventory, not to mention any legal or zoning fees depending on insurance requirements and city codes.
*another class idea, if your school has it, try taking a business geographics course
