They are knowledge and comprehension, if we don't have any of them, then we have nothing, so it's importance to have education, it's worth and really useful for us.
Knowledge is the ultimate power in the Universe so the more you know, the more powerful you are and never ever stop learning no matter how old you are. Just make sure you use this power for good and not evil as we are now experiencing throughout the world today.
No man or woman knows it all so don't worry because you probably won't either but be someone who others seek answers from and from what you see here on Blurtit, everyone seeks answers of one sort or another. Just don't ever stop learning!!
