30 years ago, Boxer Mike Tyson hired Donald Trump to be his personal financial advisor. The important lesson is:-
1. Your employee today can become your President tomorrow. So be fair and considerate to all employees.
2. Nowadays Tyson has become virtually bankrupt, having been one of the richest athletes on the world, and the Trump is currently the head of the most powerful nation on earth.
Everything was different in the past, but time can change anything.
Be positive with everyone and let go of arrogance over others.
