Associate a new word or name with a similar word or an object. Select the most important things to remember, and skip the rest. Quiz yourself on what you are supposed to remember before you come to the time when you have to use that knowledge. When you are under tension or in a time schedule, it is harder to remember things. Of course, you can also jot down lists on paper.
Some people quickly write notes on the palm of their hand.
And, of course, make sure you are eating a good diet, skipping the junk food, getting fresh air, exercise every day, and getting enough rest at night. In addition, there are also nutrition and lifestyle factors which will affect your memory. Christ loved you, or He would not have died to forgive your sins and enable you to obey His Father's law. Accept the great salvation, and rejoice that your name is written in heaven. You find you are forgetting too many things.
