I come across a fair amount of floristry students that are keen to eventually open a shop or studio once they have finished their studies, have gained reasonable experience in the industry and are in a position to invest their time (life!) and money into a retail business of their dreams.
Anyone of us who has been down this path will know that, no matter what advice you are given, how much studying you have done and no matter how much passion you have for making it work, you can never be prepared for the amount of time, effort, and dedication it takes to make a business a success. Not to mention the stress and fear of the unknown.
