What’s the best way to find a mentor?

I’m in a very fortunate position for the first time in my life and I don’t want to screw it up.

I’ve bootstrapped my entire life and am now at a point where I would really benefit from someone else’s experience to boost me on my way.

I’ve got lots of e-commerce related options and I need to make a plan for the most impact as I’m spread too thin.

Where would I even begin to find someone that could help with this kind of thing? The world is awash with half baked gurus and charlatans.

How can I find the best person for the job?

Any tips or advice greatly received – thank you!
