Next you might look into building longer journeys. 10 stages is a very good start. Then work towards a journey with 15 or 20 stages. If you find this daunting then I have to remind you of this: you haven’t practiced your 10-stage journeys (yet). The more you practice with them, the easier you will find that there actually is not that much of a difference to a 15 or 20 stage journey.
I personally work with 25 stage or 50 stage journeys. 25 can very nicely hold a decent sized chapter of a book (for study, not novel). Also, I found that 25 stages can hold the keypoints of a 2 hour lecture very neatly. It just feels right, and that’s why I have 25 stage for that. What are you using memory techniques for? Build up the journeys that suit your requirements.
I also work with journeys of 50 stages. Why? Because I found I can do it. It is as simple as that. One time I tried a journey with 100 stages. I built it, revised it, and walked the walk. Didn’t work whatsoever. I simply couldn’t hack it. It confused me. So I divided it into two times 50. I know the maths. However somehow I can hold 50 stages in my mind, and not 100. It is something I found out by trial and error.
Please do the same and find out what works for you.
Actually, to be very acurate, I work with journeys of 26 and 52 stages. Can you guess why?
Sure, that’s it: to remember a deck (half a deck) of cards. 52 cards means 52 stages. Of course!
