Personal cost bear by Leaders?

Question

the cost which a leader pays to become a leader.

Answer 1

Too vague, actually, because it varies from each individual.  There is no set amount that a Leader has to "pay" to become a leader.  In fact, join the U.S. Government as a civil servant and you can become a leader overnight, without a degree other than high school.  I have seen it happen.  Good luck.
