A couple of weeks ago I went back through all the guests we've had on the show so far and realised how very fortunate we've been to have so many fantastic guests on the show, sharing their knowledge and experience, some of them with more than 50 years of trading experience!

To be honest, I’d actually forgotten some of the topics we’d covered so far and going back through them was an excellent reminder of all the valuable information the guests had shared, so for Episode 30 I thought it might be a good idea to revisit some of the highlights from the earlier episodes so that those that haven’t heard them will go and listen to them, and those who have already listened may get some value out of hearing the highlights again.

I know when I went back through them it reminded me of some things that I wanted to test or investigate further, and I really found it a valuable exercise so I hope you do too.

This episode will cover some of the highlights from episodes 1 to 20; some of my favourites and some of yours.
