To give, or to pay before getting something, is a logical thing, too logical that it is too easily being forgotten.
People tend to take, and don't want to give, or pay the price for wat they receive or hope to receive.
To pay, it's not paying somebody else, but it's to pay for wat u are about to receive, and no one other than u urself is benefited, yet, people just don't want to give or afraid to give.
To give, it's not that it's without return, but something that u are do becoz u think it's worth giving.
To weight wat is given or paid, it not by material basis, but of mental and growth.
To risk wat is given or paid, is judged not by material basis, but by the value in which, in return, u get something that doesn't hurt u physically or mentally.
To give and take,
is how one value wat it's given and wat one hopes to receive in return.
The ratio of give:take never comes in an equivalent state, but what one perceived to be more worthy, is what makes one feels and response to that ratio in a particular situation.
Conclusion?
To give/pay before having even the simplest thought of receiving.
