There are two ways to acquires
KNOWLEDGE/WISDOM.

One way to BUY it and another is to BORROW it.

How do we buy it:
We need to pay full cost of what the whole thingy cost at full price
and sometime it even cost you double the price. When we buy it,
we spend time, money and effort.
All energy have to be place into the things we do.
Lastly when we buy it...
we buy it at the cost of learning a lesson.
The hard way to learn something.

As for BORROW:
We just need to learn from people who have experience it...
went through it and has paid for the full price...
we sometime really need to borrow from others because we does not have such time,
money and energy to spend..
and can't afford to pay for a lesson.
