As a newbie , you can use this methods
Cards - you can easily use 4 of clubs = Car
Clubs = C
Heart = H or R (your choice)
Spade = S
Diamond = D
AND If you made your Pao for cards than that is better than this.
Images = Generally all people use memory Palace for images but if you are a newbie you can start with peg system for images.
You can use different people way for making your peg
Simon peg system.
Erol Shape system
Raja pronunciation system.
Major peg system
Names = As a newbie you can easily use this approach by Ron white.
Interact name with face .
Example - Name is Brian so you assume Brain every time. And connect with face.
Different face parts =
International name - in int. names you can also use above method.
Numbers - I assume that you are a begginer so in numbers you can use major system.
After that you can use Pao or Ben system.
Words = In words you also use peg system or memory Palace.
I think for words memory Palace is a better approach for beginners or athletes.
