Knowledge is very important. I hope you know this.
A lot of people spend much time, energy and effort acquiring knowledge, which is good; because knowledge has value. However, it is not enough to acquire knowledge. It is not an end in itself. It serves no purpose if it is not put to good use.It has value only when it is used for good.If it is not used, it is wasted; and means you also wasted the time, energy and effort that you put in to acquire it.
What are you doing with the knowledge that you have acquired? Are you using or wasting it? Better use it for good; to make life better for you, others and the world.
