Choosing a mastermind group, of course, is a personal decision. Following some guidelines can help you make the right choice.
First, when investigating a potential group to join, think about the type and profile of the leaders involved. Members should fit a similar profile in terms of where they are in the trajectory of their business/income. For example, if you have been in business for 20 years, working with a group who are just starting out will not be a good fit. Look for a leader who is like-minded and has solved many of the issues you face.
Consider the group's makeup and the activities and events that are planned for the year. Do they align with your goals? Will you have time to ask the questions you have? Are the leaders like-minded, with similar company issues on which you can work jointly?
There are many ways to develop yourself professionally and create a strategic plan for your business. Joining the right mastermind group can be one of the best ways to create that opportunity in an organized and systematic fashion.
