1._____
     Most of us express dissatisfaction with our memory, especially when we want to recall some detai
l and we can't.Some examples are, an address or a telephone number, the time of a meeting,
somebody's name, etc.Even people who I think have an excellent memory, complain that they forget
things.Memory works like a bank.You can get to it, only if you put it there.If you didn't deposit it, you
can't collect it when you need it.It is described what we need to do to improve our memory in this article.
2. ____
    Recall of a particular event or detail depends on the interest we take and the importance we assign
to that detail or event, at the time when it is taking place.We remember so much more about people,
places, and topics which fascinate us.When you are greatly interested in a subject, you pay close
attention and your brain releases chemicals to form deeper "imprints" on the cells that store memory.
3.  ____
     The more active attention you pay, the more details you observe, the more you think, reason, and
comprehend, the more associations you make of what you know with what you are trying to learn, the
more you will retain and be able to recall, later on.Good memory is a state of the active mind.
4. _____
     Learn with a relaxed mind.Recall the learned material with a relaxed mind.Let's take as an example
a situation where you misplace your car keys.If you get too anxious about yourself in trying to recall
something, as is the case in this example, you are in for frustration.But, if you relax your mind, and
calmly go through the events backward, you are more likely to remember where you left them.
5. _____
     Depression can make the interest and joy less in the events surroundings us.As a result, too little
energy is left to recall anything.Some depressed persons become more anxious and depressed thinking,
"I have lost my mind." Once depression is treated, memory as a general rule, returns to the normal.
