In my final semester at the U, my professor gave our class the task of creating a business. This was to be hypothetical but we had to organize all aspects of the business as if it was going to run on it's own. My idea was a goggle case that had a battery powered fan on the side. The function would be that after a day of riding, when your gear is all wet or even in the sun if things get sweaty; you can put them in the case and they will dry.
Finances
Not only did I have to create logos and a Marketing plan, but I had to do the financials as well. This was very beneficial as I was a little unclear with this step in the business plan. I now feel perfectly comfortable with the finance aspect of a Business.
