Memory may be the most important skill you have.
It doesn't just allow you to reminisce about your experiences — it's what enables you to do everything that you had to learn at one point, from holding up your head to speaking your native language.
Memory actually takes many different forms. We know that when we store a memory, we are storing information. But what that information is and how long we retain it determines the type of memory it is.

The broadest categories of memory are short-term memory and long-term memory, based on the length of time the memory is stored.
Short-Term Memory: This refers to the very short time that you keep something in mind before either dismissing it or transferring it to long-term memory.
Long-Term Memory: This is our brain's system for storing, managing and retrieving information. We store different types of information (procedures, life experiences, language, etc.) with separate memory systems.
