Several years ago, my son asked your same question to me. here is the advice i gave him:
First, you will need a sponsor. this means a person willing to back you and your new business with cash for start-up purposes. Second, you need a financial advisor. someone to give you advice on how your business should be operated. my son married a CPA, so that solved his problem. Third, location is everything. i would not open any business on a deserted island. this is the extreme, but you would be surprised at some peoples ideas for a location. Fourth, is investment. your CPA can handle this for you.
I guess the bottomline here is: if you are single, then marry a CPA thats loaded with money and willing to invest in your idea of opening a coffee or tea shop.
This worked for my son. his idea was outstanding. after opening three additional coffee shops in the northwest, Starbucks finally bought him out.
He made a tidy profit and so can you.
