im a young and innovated guy who would like to have a night club. where do i start?

There is one easy step you can take right now. Go work in one - you really need to spend some time in the industry you plan to be an entrepreneur in. I'd look at a 3 year apprenticeship - perhaps in a couple of different ones. You can use your time spent learning the ropes while writing a business plan in the background. In 3 years time I would hope you would not say 'I have no clue where to start' but rather I have a great business plan , have worked in the industry for 3 years, and I have put together a small team and believe there is a great opportunity to open a club ...
