How to memorise a pack of cards

Today is my first day of learning to memorise a pack of cards.

I took a pack of cards with me in to work on the train and tried to memorise as many cards as I could - just the numbers not the suits.

I got to 26 cards. It took about 40 minutes

I used the method where you think of a journey and memorable places along the journey and put a card number in each place.

My biggest problem was that I got to 24 places on my chosen journey and then ran out of places. I tried places on the way home but it's a return trip and I couldn't put multiple numbers in one place - my brain couldn't do it.

So my next tasks are:

1. To find more places on the route.

2. To memorise faster.

3. To add in the suit.
