I am into my third business now. Started my first at 28, with a business publication.
It is important to do a Business Course, apart from needing capital regardless of what field you choose to go into.
It will cover everything from taxation, super, payg, how to run a successful business, importance of an accountant, growth expectation of that field, cash flow, KPI's.. There is a vast amount of area to cover to be successful within a business.
Also research other smaller companies if you can, data search for in-stance how many small businesses of your type exist as competitors.
And don't be frightened to write goals, it is a necessity, so where you want to begin is your first goal, but where would you like to end up?
YOu are allowed to dream as well, as long as you have all the right ingredients in place so you know the forcast of that dream before hand, aim at it and work for it. It doesn't have to be financially it can be as small or large as you want it to be...
Best wishes, there is something great i think about being a creative person and giving it a go.
