Everything we are today, is an outcome of our experiences of the past. Everything we will be in future, would be due to the experience we go through now.
It is important to choose our actions.
How does one make a right choice of action?
A. By Active learning - education, research, discovery, seeking etc.
B. By Passive Learning - Learning by observing.
As human beings, passive learnings come naturally to us. Example - look at the child. One does not need to teach them a language, social skills, eating habits etc. They look up to the parents, siblings, teachers, and learn by themselves.
Thus, the faster route to upgarde ourselves is by option B.
How does one achieve option B?
By Power of Associaton.
