I have invested tens of thousands of dollars with mentors because I liked them or because I thought that person could get me where I needed to go.
Do not EVER invest if that is your philosophy.
YOU are the only person who can get you where you need to go.
Mentors and guides are there to help you and shine the light on things you are not able to see yet. They are there to give you some tools.
You do not hire them because you think they can get you somewhere. If you are meant to be there, you are always going to get there. You might hire them because you think they can help you get somewhere faster than you are going to get on your own.
But it is ultimately YOU who gets you where you desire to go.
Where do you desire to go? How would it feel to know that you absolutely have the power to get there?
