Dear learner

:-*As a matter of fact Iwould say"UNDERSTAND and REMEMBER" are the two traits that we, as human being, must have for every day life, education, and profession. Without remembering how you can recall information, data or espisodic events. For example, while you were learning English grammar, let say"PRESENT SIMPLE", you thoroughly understood that. Unfortunately,as the time flies you might be no more clear. This account for the fact that you fail to REMEMBER. Similarly, without understanding how we can well encode or rigister data or information into the memory storage, the brain. For instance, again, you are learing "PRESENT SIMPLE" you don't even understand the use and meaning of the target item. Personally presuming, we understand then remember.
One more again, we shall firmly hold these qualities as they are the ingredients for survival
