According to my experience, I can suggest you the path that how can we chose the right business.
1) first, mind set:- you should have plan where to go or which business do you like to open.
2)Always remember the requirement of the customers:- when you open the business, then you should have update from the customer's demands.
3)Take the advantage of Meetings and conferencing call.
4)Cheap Entry Cost:- When you enter in the market, you should remember that the cost of your product should be cheap.
