how to empower your memory, for example, start with visual memory which  is the most important:

for example ; when you are in a certain room try to remember the three D arrangement and spatial orientation of all things present in that room, e.g. chair, desk, tv, photo hanged at the wall

and remember all details in everything for example, the photo;colors what present in that, if sea, trees, relation of everything to each other, and then go out of that room, and ask yourself

what is present  to the right what is its color, has certain shape or 

features what they are? what present e,g to the right .....etc.
