While your recent success with predicting horse racing and greyhound races is impressive, it's important to consider several factors before making a decision to quit your current job and pursue this full-time. Firstly, success in this area is not guaranteed, and there may be times when your predictions are not as accurate as you hope, resulting in significant financial losses for your subscribers. Secondly, running a successful monthly membership business model involves more than just being able to predict race results accurately. You will need to create a sustainable business plan, manage finances, marketing, and customer service, among other things.
