Well let me be the first to say, AWESOME that you went to the event. You can pay a mentor, you can take courses, etc. All that matters is you find your niche and take action.
Most people do not realize that being an investor is like saying I am in Computers. There are so many facets of "computers". You could be in Mainframes, networking, web design, web development, database administration, PC Support, etc.
Rather than trying to grasp it all, grasp one really well. Be the best at it. Just like being in a band, don't try to play all instruments. Pick one and dominate that one like Jimmy Hendrix would a guitar.
If it takes a mentor, then fine, go for it. But be sure to ask the "mentor" some very detailed quetsions. Get proof of deals they themselves have done. Ask for specifics, addresses, etc. Find out if others have utilized their service. I am sure you will always find detractors as well as those that recommend them highly.
The key is for them to show they are active now and do what they say to do. Nothing frustrates me more than the do as I say mentality. You might as well be John T. Reed, out there slamming everyone, but hasn't bought a single piece of real estate in over 20 years.
Anyway, do your due dilligence on the mentor. Not only should they be intelligent on the ways to invest, have experience in investing, but they need to be able to communicate that with you and in a manner that works well with you.
Hope that helps, I was sort of rambling on.
